Digestive System

Our digestive systems contain glands. These glands produce enzymes. Enzymes are catalysts. Catalysts make chemical reactions happen quicker and easier. Digestive enzymes help us to break down food easier. Our bodies make lots of different digestive enzymes. Each enzyme breaks down a particular food. When an enzyme has broken down one food molecule, it can then break down another molecule of the same kind. It can do this over and over again. It makes the reaction happen without being used up. In the digestive system, enzymes are produced to break down carbohydrates, proteins and fats into smaller soluble molecules from large food molecules. These spread through the tube of the small intestine and into the blood plasma (carbohydrates and proteins) or lymph (fats) and pass to the cells. The stomach makes hydrochloric acid to help the enzyme called pepsin work. Fats are difficult to digest and absorb because they are not soluble in water. To help with fat digestion the gall bladder produces bile this makes the fats smaller. This increases their surface area for enzymes to act on. In the mouth is saliva and they containing amylase produced by the salivary glands. This enzyme is used to break down starch/carbohydrates into glucose molecules. In the stomach is found Pepsin which breaks down proteins into amino acids. In the small intestine, parts of a large molecule of fat are broken down into smaller fatty acid and glycerol molecules. Below is how the different foods are digested by using enzymes: 1. Carbohydrates – Foods rich in carbohydrates include bread, potatoes, dried peas and beans, rice, pasta, fruits, and vegetables. Many of these foods contain both starch and fibre. The digestible carbohydrates such as starch and sugar are broken into simpler molecules by enzymes in the saliva, in juice produced by the pancreas, and in the lining of the small intestine. Starch is digested in two steps. First, an enzyme in the saliva and pancreatic juice breaks the starch into molecules called maltose. Then an enzyme in the lining of the small intestine splits the maltose into glucose molecules that can be absorbed into the blood. Glucose is carried through he bloodstream to the liver, where it is stored or used to provide energy for the work of the body. Sugars are digested in one step. An enzyme in the lining of the small intestine digests sucrose, also known as table sugar, into glucose and fructose, which are absorbed through the intestine into the blood. Milk contains another type of sugar, lactose, which is changed into absorbable molecules by another enzyme in the intestinal lining. 2. Protein – Foo ds such as meat, eggs, and beans consist of giant molecules of protein that must be digested by enzymes before they can be used to build and repair body tissues. An enzyme in the juice of the stomach starts the digestion of swallowed protein. Then in the small intestine, several enzymes from the pancreatic juice and the lining of the intestine complete the breakdown of huge protein molecules into small molecules called amino acids. These small molecules can be absorbed through the small intestine into the blood and then be carried to all parts of the body to build the walls and other parts of cells. 3. Fats – Fat molecules are a rich source of energy for the body. The first step in digestion of a fat such as butter is to dissolve it into the watery content of the intestine. The bile acids produced by the liver dissolve fat into tiny droplets and allow pancreatic and intestinal enzymes to break the large fat molecules into smaller ones. Some of these small molecules are fatty acids and cholesterol. The bile acids combine with the fatty acids and cholesterol and help these molecules move into the cells of the mucosa. In these cells the small molecules are formed back into large ones, most of which pass into vessels near the intestine. These small vessels carry the reformed fat to the veins of the chest, and the blood carries the fat to storage depots in different parts of the body. There are two theories on the process of chemical digestion, and they are the ‘induced fit’ and the ‘lock and key’ theory. Enzymes are specific to reactants (known as substrates). That is, enzymes only catalyze one type of reaction. Induced fit is where an enzyme almost closes around the substrate like a baseball glove around the ball. And the induced fit model says that when a substrate binds to an enzyme, the enzyme temporarily changes shape to accommodate the substrate. While the enzyme is still specific to substrates, it is not as if the substrate is a perfect fit on the active site of the enzyme. After the reaction is complete, the enzyme returns back to its original shape, ready to be reused. Lock and key is simply that the theory states that an enzymes’ active site is the exact shape of the substrate, and that the substrate neatly fits in. Also another way to look at it is that the enzyme is like a lock, and the substrate is like a key. Only specific substrate works with an enzyme, just like a specific key is required for a lock. The lock represents the active site on the enzyme, where the substrate binds. So both are substrates specific, just one model states that the enzyme moulds to fit the substrate whereas the other says that the site is already shaped around the substrate. In recent research however, the lock and key model is disputed, with the induced fit being more likely. While the induced fit model is more likely to be correct from current evidence, the lock and key model is still used because it allows a simple diagrammatic way to understand the specificity of enzymes.

A Life Lesson from My Grandma Essay

The tears rolled down profusely as I held the telephone receiver in my hand. My aunt was still on the other end, demanding that I immediately rush over to Grandma Mary’s house. At this instant, my gut instinct responded by tightening up indicating that something was definitely wrong. And it was only then; memories of her youthful days flashed across my mind, reminding me of her mantra, â€Å"You must never allow anyone to steal your joy†. And it appeared as if she was standing right beside me, but I knew it was just a fragment of my imagination. I confirmed there and then to myself, I recognized now that I had lost someone, but I would have something with me for life, the value of unconditional love my grandma often displayed amongst her family and her neighbors by extension, and she would always reiterate how much she wanted it to live on. Granny Mary was like a female Goliath. Blessed with a dark chocolate skin tone, moles and wrinkles canvassed her face which we often referred to as the storylines of her life. But the positivity she gave off could connect a grounded wire on a cold winter night. How she did it, she alone knew. I remember her making ends meet, and providing food for her family after two failed marriages. As the other half of her twin, Uncle John would pay his sister to do his laundry, cook his food and maintain the downstairs of the home which he occupied. And yes, pretty amazing how this money brought up six kids and assisted my sister and I as the two first grandchildren in the family. Not only did she raise her grand kids, but the entire neighborhood’s children were taken care of by â€Å"Aunty Mary† also, a name she would always be remembered by. I can still recall how many days the neighbor’s kids will come without food or clothes, but when they left, their tummies were filled, and late evening shower already taken. We would all surround granny as she read a bible story and explained the role of each person mentioned in the  bible. It was as if her joy was ensuring that all children were always happy and knew the value of love. And yes, this stood out most, because to this day, I share the same sentiments when dealing with my daughter and my niece, or all children I interact with on a daily basis. To this day, I could count the number of times I saw a toothy smile on her almost daunting face, after that late December afternoon when the hospital called to say my Uncle Brian passed away after being involved in a motor vehicular accident on the Solomon Hochoy Highway. She continued to emphasize that we were totally in control of our own happiness, and we should live life to the fullest always displaying love and making sure all is well with our soul as we never know when the good Lord will call us home. I remembered her kneeling to pray with her every night before we go to bed. She embedded that prayer was the answer to every problem you can ever encounter in this life and happiness is within one’s self. Grandma Mary would often have us assist her when she picked peas or fed the chickens in the backyard. We watched the chickens developed from baby chicks to mealtime. And yes, we’d joke about it when it was time to catch them to have grandma prepare some great soul f ood for us. In April 2012, I was able to display the said qualities Grandma Mary embedded in us. I gave birth to a still born baby boy, and all I saw after giving birth, was my grand-mother’s face. How she’d often say God is ever to wise to make a mistake, and God sees what we don’t. Although I didn’t want to hear that at that time of grief, I clearly remembered dreaming her one night, giving me confirmation that all would be well, and continue to love and have faith in God. And as I thought about her the morning after I was discharged from the hospital, I made hot cocoa, and the aroma took me back to twenty years ago when my grandmother was alive. We’d wake up to the aroma of hot cocoa and her favorite Jim Reeve would be blasting through the house, â€Å"If heaven’s not my home, then Lord what will I do?† And it was as if she strengthened me to look forward and not regret. I remembered her mantra, and I did not allow the death of my son to steal my joy. I still had my daughter to brighten up my days, and prayers assisted me in trusting and believing that God had better plans for me. As an individual, I can associate part of my grandmother’s journey to that of mine. No mother comes on this earth with the intentions of having to bury their own child, but all in all, life has to go on. And not just go on, but I am in control of my own joy. The qualities she left us with have continued to reign throughout my family, and every time I sit to tell a story about Grandma Mary, I can safely associate her with love, faith and God. The aroma of hot cocoa today brings a smile on my face, and each time I hear a Jim Reeve play, I’ll see her wrinkled face. There is no greater joy in having a loved one live on although they are no longer with us in body. I am one hundred percent guaranteed she is indeed happy with the positive value we continue to display. And the deep voice ringing through my head, â€Å"You must never allow anyone to steal your joy†.

Describing of the Sarbanes-Oxley Act

1. In two to three paragraphs, describe the Sarbanes-Oxley Act and why it is important to the accounting profession. (15 points) Sarbanes-Oxley Act was created in order to ensure that controls were implemented and monitored by the regulating authority. Congress wanted to make sure that there was a specific standard and guideline for companies to follow in order to prevent fraud at such a large scale. When followed correctly there are controls set in place that are internal which are governed by the managers and checked upon by the Federal regulatory authorities.This act was passed in 2002, prior to then the rules were more relaxed and when the crisis occurred with Enron that was a breaking point for the American people, especially those who lost a lot of money. Needless to say this just made it harder for fraud to occur. There were and still are several grey areas that the players involved exploit.2. Name and briefly describe the five components of COSO’s internal control fram ework. (10 points) The five components of COSO are as follows: a. Control Environment: Basically means that the leaders of the organization set the tone for ethics and enforce them with a code of conduct followed by consequences when not abided by. b. Risk assessment: this just means they check there controls for weaknesses regularly and fix any discrepancies with stronger controls. c. Control activities: These are segregation of duties, account reconciliations, and info processing controls. They are considered internal controls as well that protect the processes in place. d. Information and communication: The internal and external reporting process. The text book stated that it includes technology assessments as well.3. Describe the relationship between the Sarbanes-Oxley Act and COSO. (10 points) COSO is used to check in on the organizations and offer guidelines for them to follow when setting upo their controls. If all five elements are followed then they will not have much to wo rry about when auditing occurs and fraud would be less likely.4. Tom Jackson is a CPA who really likes to go to Las Vegas, play poker, and bet on football games. Tom knows that the accounting profession disapproves of gambling, but because he spends a lot of time studying sports facts and how to win at poker, he feels that he is simply making educated decisions based on facts. He says that this is no different from using accounting information to buy stocks. Use the fraud triangle as a basis to comment on Tom’s gambling activities. (15 points) In this case Tom has all of the elements in place to commit fraud. He has the opportunity because of the nature of his business.He has already decided that gambling excessively is ok because it is a calculated risk. Not realizing he is putting himself in a position where the pressure will come into place when he does lose. Debt is always looked at when being evaluated for sensitive positions that deal with national security or money inv olvement. Even if it is just a public trust clearance that the person is seeking on order to get the position they still will review your credit history at a minimum.

Thessalonians

Thessalonians Thessalonians is based on two different letters that was written to the Christian community in Thessalonica. The purpose of the first letter was to clear up some of the misunderstandings about the return of Christ. The second letters purpose was to still clear up some of the misunderstandings about the Day of the Lord for they thought the day had already come. The first letter to the Christian community was sent from Paul, Silvanus, and Timothy, though Paul was the main author. Paul was writing to them to clear up their misunderstandings about the return of Christ, also considers it as instructions in holy living.Paul wrote about his longing to visit the church in Thessalonica but he couldn’t because Satan had stopped them (1 Thessalonians 2:18). Though some believe the second letter to the Christian community is wrote by Paul others do not. Many scholars point out how the writing style, vocabulary, and structure of the 2 Thessalonians are too similar to the 1 Th essalonians. They suggest that it was written by an anonymous author 50 years after Paul’s death, using the 1 Thessalonians as their guideline. The early witnesses for the belief that Paul is not the author are strong and include Igantius, Justin, and Polycarp.Although there seems to be different beliefs on who wrote the 2 Thessalonians, no one will really know. Paul’s reasoning for both letters seems to be along the same point to clear up the misunderstanding of the return of Christ and how the Christian community of Thessalonica was being persecuted for they believed that the Day of the Lord had already come. The first book of Thessalonians was suspected to have been written in 49-51 CE when Paul was on his Corinthian mission. (Acts 17-18) records Paul’s visits to Thessalonica and then to Athens, and to Corinth, which is how they correspond the date of the letter.It has been read that Paul did not starting writing his letters until he started traveling to the various places. Therefore they based these dates on traveling companions and cross referenced between 1 Thessalonians and Acts. There are many arguments about when the 2 Thessalonians was written, because they believe that Paul did not write the letter. Depending on the actual authorship of the letter would be what the date of it was written would depend on. Stating that if the letter was written by someone else but in Paul’s name, it is said that it may have been wrote in the late first or perhaps the early second CE.With that being said it is not sure on the exact date or time frame that the 2 Thessalonians was wrote. With many opinions about the date and who wrote the 2 Thessalonians it will not be known until the authorship of the letter is cleared up. There is enough evidence on when 1 Thessalonians was written. How they correspond the dates to when he was traveling and that he was on his mission in Corinthian, which would be around the 49-51 CE. Paul was writing the let ter to the churches of Thessalonica which is the capital of the Roman province of Macedonia.His purpose of writing was to praise them on their â€Å"faith and love† that Timothy had brought and to focus on the instruction on how to live their Christian lives. Paul was writing this letter while he was on his mission in Corinthian where he was farther south in the province of Achaia. He wants the letter to be read aloud â€Å"to all his brothers† which means all his believers in Thessalonica. In 1 Thessalonians 4:3-4 it is confirmed of the conclusion that the churches of Thessalonica was mostly composed of gentile believers.Unlike Jews the Roman gentiles was notorious for being sexually immoral which is what Paul wanted the Thessalonians to keep them from. Both of the letters is written to the same audience the Christians of the Thessalonica churches. Without knowing who the true author of the second letter is it, there isn’t a for sure location on where the lette r was written although it is believed to be in Corinth if Paul did write the letter. Paul’s purpose of the first letter was to correct a misunderstanding about the return of Christ. To also urge his readers to respect their leaders, his could suggest that there was some tension among the people in the churches. He expressed his satisfaction over the progress that the community had made and his joy. His Jewish opponents apparently had made accusations about his cowardice and self-seeking charges brought against him. He points out the importance of Christian morality, to safeguard them from attempts to make new converts to Christianity and to revert to their old standards. Paul’s purpose of the second letter was to clear up any misunderstandings that came in the first letter.For he talked about the second coming of Christ, so those people believed in the Thessalonica churches that the coming of Christ was soon. Some quite their jobs, refused to work, and become idle busy bodies and gossips, so Paul wrote to them also to encourage them to go back to work. The Christians were being persecuted by the Jews for they were hardened by the hearts and jealous of their success. He was telling them that when Christ returned for judgment the ones that was afflicting pain upon them would be punished for their doings.The purpose of both letters is nearly the same, wanting to tell them of the second coming of Christ and live their lives the way that he has instructed them too. The only difference was to clear things up that many had misread in the second letter for they misbelieved that the coming of Christ was soon. For Paul did not know when the actual coming would be but he was warning them of it so they would be ready for judgment day. The first letter from Paul is unique because through most of the letter it is devoted to his prayer and thanksgiving for their faith in Christ.He writes to them concerned for his people and thankful for the time that he has spen t with them. In his letter he uses â€Å"You know† and â€Å"You Remember† repeatedly to remind them of the teaching he did to them. This shows how much of a personal relationship he had with the Thessalonian churches. He makes it clear in his letter that he is speaking to the ones that are followers of Jesus Christ. The second letter from Paul is unique as well. He still praises them for their faith in him and in Christ. He tells them of importance of letting their faith and love to continue to grow to be of examples for other churches.Despite all the suffering and pain they have been going through to not let their lives drift away from Christ. Explains the importance of getting prepared for the second coming of Christ and how gives them information about the apostle’s beliefs in when the second coming could be. Both of letters show Paul’s faith and love in the Thessalonians churches. He proves to those that he is very expectant of these churches to be e xamples for other churches through these letters. That despite the difficulties and pain that some go through that believing in Christ he will help you find your way out as long as you have faith and love in him.Throughout doing this paper I have learned many different opinions of whether Paul actually wrote the second letter or that he didn’t. I have been able to read about how Paul outpours his love and faith for the Thessalonian churches and that he wants them to live their lives for Christ. One of the key points that I have learned is that although you may struggle with difficulties and pain that if you have faith and love in Christ that he will help you find the way to survive these obstacles.Works Cited Coogan, Michael D. , et al. , eds.

Toxicological poisoning Essay Example | Topics and Well Written Essays - 250 words

Toxicological poisoning - Essay Example The potential of carbon monoxide for toxicological poisoning is manifested when it is inhaled by members of the household. The harmful effect caused by the inhalation of carbon monoxide is that these toxic chemical compounds combines with the hemoglobin in the blood, thus preventing the body from absorbing oxygen and the adverse result is asphyxiation. The treatment of asphyxiation is to make use of artificial respiration to prevent the patient from dying (Klaasen, 2001). Dishwashing liquids are usually in the kitchen and are used for washing utensils. These dishwashing liquids are actually toxic in nature and are poisonous when mistakenly swallowed. In order to prevent people from mistakenly swallowing these dishwashing liquids, they should be put in their right containers. The utensils that are washed with these dishwashing liquids should also be properly rinsed with water in order to remove any sign of the dishwashing liquids from them. These precautions would go a long way in red ucing the harmful effects caused by swallowing these dishwashing liquids. Note that people that mistakenly swallow these dishwashing liquids usually complain of stomach cramps and other stomach related illnesses. In order to reduce the effect of swallowing these dishwashing liquids, one should use purgatives (Klaasen, 2001). Laundry detergents as the name implies are chemical substances that are used for laundry purposes.

Decision Support and Business Intelligence systems Essay

Decision Support and Business Intelligence systems - Essay Example ta hub, storing not only current data, but also historical data to be used for developing trending reports so that the management can use the reports for comparisons, even if it the comparisons are annual, quarterly or even semi-annual. Subject oriented implies that data warehouse is utilized when examining specific subject field. For instance, in business, production can be the specific filed of examination. Integrated implies that a data warehouse incorporates data from a number of data source, for instance, from sales department and production department identify product A differently, however, the data warehouse will incorporate the two to identify the product in a single way. Time invariant implies that data, whether kept for 2 months, 7 months or even after a year is retrievable. Non updatable implies that once the data is entered into the database, it will not be mutilated and would not be changed, and, as a result, the historical data shall never be altered. Text mining refers to the unearthing and extraction of interesting, non trivial knowledge free from free and unstructured text (Kao & Poteet, 2007). The process encompasses information retrieval, and that is, document and website retrieval and even to classification and clustering of text. Natural language Processing, on the other hand, implies the endeavor to extract a complete meaning representation from such free text (Kao & Poteet, 2007). Natural Language processing has been developed to conform to a number of techniques that are naturally syntactically parsed utilizing information from proper grammar and lexicon, thereafter the ensuing information is then deduced semantically and thereafter applied to produce data. NLP can be profound, spanning every corner of the sentence, or even thin , straddling just few passages or phrases within sentences, and even utilize statistical ways to remove vagueness in word senses of the same sentence. The unassuming challenge posed to the development of NLP

Effects of carbon dioxide Essay Example | Topics and Well Written Essays - 250 words

Effects of carbon dioxide - Essay Example While the atmosphere is composed of carbon dioxide, and it is something that humans and other living things do breath in at a constant rate, too much of it in our atmosphere is a bad thing. Carbon dioxide plays a role in the formation of greenhouse gases, herein creating the greenhouse effect (Luo, 1999). The greenhouse effect, in short, involves an atmosphere containing gases that soak up and emit radiation. Carbon dioxide makes up approximately twenty-six percent of the gases needed for a greenhouse effect to take place (Weart, 2009). When the greenhouse effect takes place, so does the concept of global warming; the two processes go hand-in-hand with each other, with the greenhouse effect leading to global warming. As aforementioned, carbon dioxide also has positive effects on the environment. The biggest one is the creation of oxygen. Plants absorb carbon dioxide, convert it to oxygen, and release it back into the environment. We, as humans, then breathe in the oxygen, and when we release the oxygen, it becomes carbon dioxide again. It becomes a never-ending cycle between plants and humans. Furthermore, carbon dioxide aids in the process of photosynthesis, feeding the plants and keeping them alive (â€Å"Carbon Dioxide†). Without carbon dioxide, there can be no photosynthesis of the plants, and therefore no food to keep them alive. Without living plants, there is nothing to convert carbon dioxide into oxygen for human beings and animals to breathe. We become dependent on each other to live. Again, it becomes a cycle that must be adhered
