BioChem C785 - WGU - Module 5 - all questions with complete solutions What vitamin does not travel through the bloodstream in the form of a lipid micelle? ✔✔Vitamin C Which lipid has a 4-ring ... structure? ✔✔Sterol Which of the following situations is MOST likely to increase the rate of beta oxidation? ✔✔fasting A patient who is on a no-fat diet is at particular risk of deficiency in: ✔✔Vitamin A During starvation, triglycerides can help supply some of the body's glucose needs. Which breakdown product of triglycerides can be used to make glucose? ✔✔glycerol CH3(CH2)6CH=CH(CH2)2COOH ✔✔liquid at the lowest temperature Describe the steps involved in fatty acid synthesis ✔✔Acetyl-CoA is transported to the cytoplasm - Biotin transfers a carboxylate group to acetyl-CoA - the malonyl group is transferred to a carrier protein - malonyl ACP combines with acetyl-CoA, - malonyl-CoA is added repeatedly to the growing fatty acid What fatty acid will produce 8 Acetyl CoA molecules after it is completely metabolized via beta oxidation? ✔✔CH3(CH2)4CH=CH(CH2)4CH=CH(CH2)8COOH Which set of molecules are produced by the beta oxidation of fatty acids? ✔✔Acetyl CoA, NADH, FADH2 Gastric bypass surgery results in an increase in the production of GLP-1, a peptide that promotes insulin secretion. This is thought to be associated with the tendency for these patients' type II diabetes to resolve after the surgery. If a gastric bypass patient has a mutation in GLP-1 that impairs its function, what is to be expected? ✔✔The patient would have reduced insulin secretion compared to patients with normal GLP-1, and this reduction results in increased fatty acid oxidation Through mandatory state testing, a 2-day-old newborn is found to have a medium chain acyl-COA dehydrogenase deficiency (MCADD). This enzyme deficiency interferes with the baby's ability to break down medium chain fatty acids via beta oxidation. Her parents need to be given spec [Show More]
