Question

Question 33 (2.5 points) Saved Which of the following is true regarding fatty acid synthesis? This is a mitochondrial process. The primary product of this pathway is a 12C saturated fatty acid The rate-limiting step of this pathway forms the four-carbon product, malate. The main enzyme in fatty acid synthesis does not form an unsaturated direct product. Question 34 (2.5 points) Saved Which of the following is an essential fatty acid in humans? Palmitate Oleate Linolenate Lanosterol Question 35 (2.5 points) Saved Which enzyme in the TCA cycle makes ATP (or GTP, in some cells)? Aconitase O Malate dehydrogenase Succinate dehydrogenase O Succinyl CoA Synthetase Question 36 (2.5 points) Saved

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!

DUE AT MIDNIGHT PLEASE HELP ASAP

Answer 1

33. The answer is correct. The main enzyme in fatty acid synthesis does not form an unsaturated direct product. this is done by accesory enzyme such as reductase.

34. The answer is correct. linolenate is a polyunsaturated fatty acid.

35. The answer is correct. Suucinate CoA synthetase produce ATP.

36. The answer is correct.

37. The answer is wrong. Correct answer is none of the above. If the blood glucose level is low then the glycogenolysis will happen but glycogen synthase is a gycogenesis enzyme which will be active when blood glucose level is high. Rest of the enzymes are all participating in fatty acid biosynthesis which will be shut down in low blood glucose level.

38. The answer is wrong. The answer is non- oxidative pentose phosphate pathway only and in the forward direction. From ribulose 5 -phospahte,ribose 5 phosphate is formed in the second step. So this is a forward reaction.
