Feedback inhibition is important for the regulation of many metabolic pathways. Which of the following are examples of feedback inhibition? Arsenic binds to pyruvate dehydrogenase and inhibits the enzyme. The last enzyme in glycolysis is activated by the intermediates of glycolysis. The lac operon is not transcribed when there is no lactose present. The production of tryptophan is halted by presence of excess tryptophan. The beginning of glycolysis is inhibited by high levels of ATP in the cell.

g Feedback inhibition is important for the regulation of many metabolic pathways. Which of the statements are examples of feedback inhibition? The beginning of glycolysis is inhibited by high levels of ATP in the cell. The lac operon is not transcribed when there is no lactose present. An intermediate of glycolysis activates an enzyme downstream in the pathway. Arsenic binds to pyruvate dehydrogenase and inhibits the enzyme. The production of isoleucine is halted by the presence of excess isoleucine.
