- There are several processes that take place from the moment food enters our mouth until it is completely digested and used for energy. Using approximately 400-500 words, describe in detail and in order of process the mechanical (stomach and intestine)and chemical (gastric acid and enzymes) digestion of eating a grilled chicken sandwich with mayonnaise, lettuce, and tomatoes. Note what role the pancreas, gallbladder, and liver play in digestion of the ingredients? From what ingredients is your body deriving its energy and how many basic calories from the macronutrients ingested? Include at least two scholarly references (using APA formatting and style) to guide your answers (note that you can use your textbook as one of your references).create a flow chart or diagram to illustrate the digestion and absorption of carbohydrates. The starting carbohydrate molecules are starch, sucrose, lactose, glycogen, and cellulose. What will happen to these carbohydrates once we ingest them? Include the following from your flow chart or diagram: 1) the location or site where the digestion or absorption occurs 2) the enzymes 3) the products generated at each site or locationcreate a flow chart or diagram to illustrate the digestion and absorption of proteins. What will happen to the meat once we ingest them? Include the following from your flow chart or diagram: 1) the location or site where the digestion or absorption occurs 2) the enzymes 3) the products generated at each site or location
- Carbohydrate comes in the form of Sugar, Starch, Glycogen, and Fiber. What are the difference(s) between simple and complex carbohydrate? Give an example of each types of simple and complex carbohydrate. What are the main functions of carbohydrate in the body? Briefly list the steps of carbohydrate digestion from the mouth to the large intestine.Which of the following best describe protein digestion? . Protein digestion is a hydrolytic process regulated by pH changes in the gastro-intestinal track, and hormonal and enzyme releases at various stages of digestion. .. Protein digestion occurs during the gastric phase of digestion starting in the stomach. Protein digestion cleaves peptide bonds releasing peptides, and amino acids Protein digestion is a hydrolytic process involving proteases/ proteinases Protein digestion occurs at the active site of proteases and is effected by the catalytic triads.Barb suffers from Crohn’s disease, a regional inflammation of the intestine that is thought to have some genetic basis, although the actual cause remains unknown. When the disease flares up, she experiences abdominal pain,weight loss, and anemia. Which part(s) of the intestine is (are) probably involved, and what might be the causes of her signs and symptoms?
- During the _____ phase of digestion, blood glucose levels drop and our body must depend on stored energy. The sympathetic nervous system directs the pancreas to release glucagon, which causes glycogen to be transformed back into glucose. Glucagon also causes stored fat and glycogen to be released into the bloodstream. A) fasting B) exhaustion C) resistenceWith the two menus provided, answer the question below: Menu 1: Roasted chicken with mashed potatoes (mostly proteins and carbohydrates) Menu 2: Pasta with alfredo saude and cheese (mostly carbohydrates, dairy products and lipids) Question: Describe the steps in the chemical digestion of the main constituents of your meal (name the enzyme (s) and other secretions involved, and what cells secrete them), all of that from the beginning to the end of digestion.Arrange the following statements regarding the processes of protein metabolism starting from Step 1 to Step 10. Conversion of pepsinogen to pepsin by HCI • Active transport takes place • Conversion to individual amino acids Glutamate becomes alpha-ketoglutarate Mechanical digestion to go to the small intestines • Shuffling of amino group to generate glutamate • Conversion of proteins to simpler polypeptides Removal of basic and acidic functional groups Enters the Kreb Cycle • Acidic denaturation and hydrolysis of proteins
- In order for the food to be processed and absorbed in an optimal way, there are several feedback mechanisms. One of the most important starts when the food reaches the small intestine, this is sometimes also called the intestinal phase. Describe what happens if the food that reaches the duodenum contains a lot of fat and a lot of protein. The answer must include: Which different mechanisms are affected by the respective stimuli (fat and protein) and how (increases or decreases the activity). What cell type senses stimuli and how these cells react. Which different signaling pathways (including the signaling substances involved) control the different mechanisms that are affected by the respective stimuli. Feel free to draw.Describe what happens to the food types specified below as they pass through the following zones of the Digestive system Mouth, Stomach, Small intestines, large Intestines. Specify the food example (Carbo-rich food)rice, (protein rich) chicken adobo, (fat rich food) crispy pata, Identify the enzyme that catalyzed the digestion process and the source enclosed in parenthesis. 1 Carbohydrate-rich food 2. Protein-rich food 3. Fat/lipid-rich foodWhich of the following is NOT an enzyme secreted into the small intestine as an aid to chemical digestion: A) Bile B) Lipase D) Amylase
