Correct Answer: Sterol Which of the following situations is MOST likely to increase the rate of beta oxidation? Correct Answer: fasting A patient who is on a no-fat diet is at particular risk of deficiency in: Correct 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? Correct Answer: glycerol CH3(CH2)6CH=CH(CH2)2COOH Correct Answer: liquid at the lowest temperature Describe the steps involved in fatty acid synthesis Correct 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? Correct Answer: CH3(CH2)4CH=CH(CH2)4CH=CH(CH2)8COOH Which set of molecules are produced by the beta oxidation of fatty acids? Correct Answer: A
