Glucagon and ___ stimulate the breakdown of triacylglycerols by activation of a hormone-sensitive lipase. What molecule is used to transport acetyl groups from the matrix to the cytoplasm? A) acetyl-carnitine B) succinyl CoA C) oxaloacetate D) alpha-ketoglutarate E) citrateExplanation / Answer
18. A. Pyruvate
19. The coenzyme that provide reduvtive power for fatty acid synthesis is Acetyl Coenzyme A
20. The function of Acyl coenzyme A synthetase is ATP dependent Activation of fatty acid using CO A
21. The enzyme methylmalonyl coenzyme A mutase contains Riboflavin as a derivative of as its coenzyme.
22. Triglycerols have an ecxcellent design for energy stores because they are anhydrous and they are highly reduced.
23. Glucagon and Insulin stimulate the breakdown of triglycerols by activation of hormone sensitive lipase
24. Citrate is used to transfer acetyl group from matrix to cytoplasm.
