- What class of enzymes catalyzes the majority of the reactions involved in carbohydrate digestion?Which of the following is NOT an enzyme secreted into the small intestine as an aid to chemical digestion: A) Bile B) Lipase D) AmylaseThe synthesis of glucose from noncarbohydrates is called (a) glycolysis. (b) lipolysis. (c) gluconeogenesis. (d) beta-oxidation.
- What type of reaction must take place in order for chemical digestion to occur?In which part of the digestive system the absorption of following substances takes place?(a) Certain drugs(b) Glucose, fructose and fatty acids(c) Water, some minerals and drugs(d) Simple sugar and alcoholWhat happens to the products of the digestion of lipids? They are absorbed into a: O a) capillary and transported by the blood to the liver b) capillary and transported by the blood to the heart O c) lacteal and transported by the lymph to the thoracic duct O d) lacteal and transported by the blood to the liver via the hepatic portal system
- Determine the initial site of digestion (chemically) of the following:(1) Carbohydrates(2) Lipids(3) ProteinsThe removal of an amino group in a reaction that generates an ammonium ion is called: (a) ketoacidosis. (b) transamination. (c) deamination. (d) denaturation.Fatty acids and triglycerides are an important source of nutrition and a dense form of stored energy. Digestion of fats yields more energy per gram than digestion of carbohydrates. In the first step of fatty acid digestion, the carboxylic acid of a fatty acid is activated to a fatty acyl-CoA. This activation step A) requires the input of energy from ATP. B) requires the input of energy from NADH. C) releases energy which is captured in the form of ATP. D) releases energy which is captured in the form of NADH.
- Provide an explanation for the following observations;(a)fat are broken down into fatty acids and monoglycerides in the intestinal lumen but appear later in the blood as fat droplets.(b)how bile acids the digestive process even though it contains no enzymes .Fat digestion yields fatty acids and glycerol.Protein digestion yields amino acids. Bothdigestive processes(A) occur inside cells in most animals.(B) add a water molecule to break bonds.(C) require a low pH resulting from HClproduction.(D) consume ATPSuppose you have a test tube containing olive oil and pancreatic lipase in a pH 7.0 buffer incubating at 37°C for 1 hour. a) Identify two different observations or measurements you can make in order to determine whether digestion of the oil occurred. b) Do you think digestion occurs under these conditions? What could have made digestion more efficient?
