The first step of β oxidation is: hydration by enoyl CoA hydrase. oxidation by FAD. activation by CoA. oxidation by NAD+. thiolysis by CoA.

Which statement is TRUE regarding the glycolytic pathway? It includes five phosphate transfer reactions.   All of the enzymes that are regulated by product inhibition.   It includes reactions catalyzed by three isomerase enzymes.   All of the enzymes are regulated by high ATP concentratrion

[References) Which of the following statements explains why acetyl-CoA Iis considered the central molecule of metabolism? (Select all that apply.) O The addition of acetyl-CoA to compounds stabilises them. Acetyl-CoA contains a thioester bond that makes it one of the high energy compounds in metabolic pathways. O Acetyl-CoA is an inhibitor that plays a central role in regulating metabolic pathways. O Acetyl-CoA feeds directly into the citric acid cycle. U None of the above.

In TCA cycle, the enzyme that contains an FAD prosthetic group is—     malate dehydrogenase.     succinyl-CoA synthetase.     succinate dehydrogenase.     isocitrate dehydrogenase.     fumarase.

Taking in consideration glycolysis, the pyruvate dehydrogenase complex, and the citric acid cycle, how many FAD molecules are reduced from a single molecules of glucose       2 FAD       4 FAD       1 FAD       3 FAD None of the above
