Digestion

body. You might find yourself asking, what does blood have to do with digestion, respiration and circulation? Hopefully, after the presentation all of your questions will be answered. When a person thinks of digestion they usually think about what happens in the stomach. A lot has happened to digest the food way before it gets to the stomach. It starts in the mouth or oral cavity. It is a process called mechanical digestion. First, Mastication begins. Mastication is the chewing of the food

The Process of Digestion Over the course of time there have been many difficult questions and theories about everyday life. Using physiology & chemistry, those questions have been able to be answered. From the mixture of gases in the air we breathe to the organic substance of plastic or paper, chemistry can be seen everywhere. However, most people mistook the power of chemistry in our own bodies. How is it that a simple slice of bread, once consumed, can turn into fuel for the human

enzymes? What specifically is the role of an enzyme in digestion? Enzymes are working proteins that facilitate chemical reactions without being changed in the process. Organs of the digestive system excrete digestive juices, which contain enzymes that break the bonds of nutrients that can be absorbed. 2. Trace the path of a cheeseburger and fries through the digestive tract. Indicate each place where mechanical digestion, chemical digestion, and absorption occurs FOR EACH NUTRIENT (carbohydrates

Digestion Lab Abstract – The purpose of this lab was to understand how different solutions played a role in the digestion protein. By looking at different variables, such as temperature, and pH we’re capable of understanding just how certain substances functioned and when they didn’t. The data for all labs are clear and concise and give a clear understanding of what solutions work best. All three labs were placed in a warm water bath set at 37’C to stimulate the reaction as if it were taking place

Week 7 Digestion Lecture Study Guide Based on information found in the lecture folder or other sources, answer the following questions. 1. What is digestion? Digestion is the mechanical and chemical breakdown of food into usable molecules 2. List some other names of the digestive tract. Alimentary Canal (GI Tract) 3. Explain where and how the mechanical breakdown of food occurs. Teeth begin digestion mechanically, Chewing (“mastication”) breaks apart food, 2 sets

Digestion and Leaky Gut Why is Digestion Important? Healthy digestion is crucial for health and wellbeing. Everything we ingest has a purpose, either it will nourish the body and act as fuel or will lead to various health conditions, some can be minor but while some lead to chronic disease. If our digestive system is not working properly, even with the best diet, nutrient absorption will be reduced. A huge function of digestion is to breakdown food, reducing it basic nutrients to be used as

Digestion of Cheetos It’s a typical day. After school you get home and you are starving, but you just want a snack. “What should I eat?,” you ask yourself. Then, after looking through the cabinets for a few minutes, you find Cheetos and decide to eat a few. With just the presence of those Cheetos in your sight, the digestion process begins in your 9 meter long digestive tract. Crunch, Crunch, Crunch. As you munch on those first few Cheetos the digestion process begins in your mouth.

necessary for the digestion of lipids, carbohydrates, and proteins. It was hypothesized that certain conditions are necessary in order for digestion to occur. For the lipid test, it was predicted that the presence of pancreatic lipase would be required for digestion and that the addition of bile salts would speed up the rate of digestion. Digestion occurred in tubes 1-3 because they changed color from blue to green, indicating that fatty acids were released as a result of digestion. Digestion occurred in

pepsin(5 % solution)+5 ml water | 5 ml HCl(0.5 %)+5 ml water | 5 ml pepsin(5 % solution)+5 ml NaOH(0.5 %) | 3. The tubes are allowed to incubate in a 37˚C water bath for 1 hour. The final pH of the solutions is tested and the amount of protein digestion is estimated using a scale of (+++), (++), (+), and (-) by

Digestion The food sample is digested by heating it in the presence of sulfuric acid (an oxidizing agent which digests the food), anhydrous sodium sulfate (to speed up the reaction by raising the boiling point), and a catalyst, in this case the Kjeldahl tablets, to speed up the reaction. This process converts any nitrogen in the food (other than in the form of nitrates or nitrites) into ammonia, and other organic matter to C02 and H20. Ammonia gas is not released in an acid solution because the
