Why does acetyl CoA, a product of fatty acid catabolism, influence the pyruvate dehydrogenase complex (PDH),...
Why does acetyl CoA, a product of fatty acid catabolism, influence the pyruvate dehydrogenase complex (PDH), a control point in carbohydrate catabolism? When fatty acid breakdown is high, ADP is low and PDH is inhibited by phosphatase activity. When fatty acid breakdown is inhibited, PDH is inhibited by acetyl CoA due to phosphatase activity. When fatty acid breakdown is high, NADH levels drop, causing an increase in E2 activity. When fatty acid breakdown is high, PDH is inhibited by acetyl...

1.Predict the effect of a large amount of acetyl-CoA on the activity of pyruvate dehydrogenase and the rate of glycolysis. Note: pyruvate dehydrogenase is the enzyme that catalyzes the formation of acetyl-CoA from pyruvate. a. Pyruvate dehydrogenase activity will decrease while the rate of glycolysis will increase. b. Both pyruvate dehydrogenase activity and the rate of glycolysis will decrease. c. Pyruvate dehydrogenase activity will increase while the rate of glycolysis will decrease. d. The rate of glycolysis will increase, thereby,...
