Question

Which of the following is true regarding glycogen metabolism? O Glycogen synthase is activated by phosporylation. Glycogen phosphorylase kinase activates glycogen phosphorylase through phosphorylation. The activation of PKA is downstream of insulin signaling in muscle cells. O Glycogen phosphorylase releases free glucose from the ends of glycogen Question 7 (2.5 points) Saved Which of the following is true regarding fatty acid synthesis? O Fatty acid synthesis occurs in the mitochondrial matrix. Citrate is a negative regulator of fatty acid synthesis. Fatty acid synthesis is primarily regulated through the regulation of thiolase activity of fatty acid synthase. O High concentrations of palmitate can prevent citrate export from the mitochondrial matrix. Question 8 (2.5 points) Saved The main rate-limiting step for fatty acid breakdown is the transfer of the fatty acyl group to carnitine, with release of COA True O False Question 9 (2.5 points) Saved In the glycerol 3-phosphate shuttle, electrons from NADH in the cytosol will initially enter the electron transport chain by reducing: O Complex III O Ubiquinone Cytochrome O Complex II

Hi the automatic grader for my biochemistry assignment is saying im getting things wrong but i cannot figure out which. Please tell me which are wrong with corrected answers. Thanks!

Answer 1

6. The answer is correct. glycogen phosphorylase activated by phoshorylation.

7. The answer is correct. palmitoyl CoA is a feed back inhibitor.

8. The answer is correct

9. The answer is correct

12. The answer is correct. Cytochrome C, ubiquionone are moblie elements in ETC.

13. The answer is correct

14. The answer is correct. phosphatidic acids are the precursor for phospholipids and glycerolipids.

15. The answer is wrong. Apolipoprotein CII is present in VLDL not in LDL. The coreect answer is Nascent chylomicrons travel in the lymphatic system to blood stream where they mature.
