BioChem C785 - WGU - Module 5 - all questions 1.What vitamin does not travel through the bloodstream in the form of a
lipid micelle?: Vitamin C
2.Which lipid has a 4-ring structure?: Sterol
3.Which of the following situations is MOST likely to increase the rate of
beta oxidation?: fasting
4.A patient who is on a no-fat diet is at particular risk of deficiency in:: Vita- min A 5.During starvation, triglycerides can help supply some of the body's glu- cose needs. Which breakdown product of triglycerides can be used to
make glucose?: glycerol
6.CH3(CH2)6CH=CH(CH2)2COOH: liquid at the lowest temperature
7.Describe the steps involved in fatty acid synthesis: Acetyl-CoA is
transport- ed 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 8.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 1 / 2
- / 3
9.Which set of molecules are produced by the beta oxidation of fatty acids?-
: Acetyl CoA, NADH, FADH2
10.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 11.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 specific
instructions on what the baby can ingest. What is correct?: She will not be
able to utilize adipose tissue for ATP production as effectively as a baby without the disorder 12.Which of the following contributes to the development of ketoacidosis
in a diabetic patient: A reduction in citric acid cycle intermediates,
which decreases
