Question

Quizplus · Accepted Answer

A decrease in the ATP:ADP ratio indicates a low energy state in the cell. This would result in an increase in the activity of glycolysis to generate more ATP. The enzyme phosphofructokinase is a key regulatory enzyme in the glycolytic pathway, and an increase in its activity would result in increased flux through glycolysis. Decreased ATP:ADP ratio would not affect electron transport and oxidative phosphorylation as these processes are regulated by different mechanisms. Isocitrate dehydrogenase is not directly regulated by changes in ATP:ADP ratio, but by feedback inhibition from NADH and ATP.
