BioChem C785 - WGU - Module 5 - all questions and answers latest 2024 What vitamin does not travel through the bloodstream in the form of a lipid micelle? - Answer ️️ -Vitamin C Which lipid has a 4-ring structure? - Answer ️️ -Sterol Which of the following situations is MOST likely to increase the rate of beta oxidation? - Answer ️️ -fasting A patient who is on a no-fat diet is at particular risk of deficiency in: - Answer ️️ -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? - Answer ️️ -glycerol CH3(CH2)6CH=CH(CH2)2COOH - Answer ️️ -liquid at the lowest temperature Describe the steps involved in fatty acid synthesis - Answer ️️ -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? - Answer ️️ -CH3(CH2)4CH=CH(CH2)4CH=CH(CH2)8COOH Which set of molecules are produced by the beta oxidation of fatty acids? - Answer ️️ -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? - Answer ️️ -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
