Question

Quizplus · Accepted Answer

ATP and NADH are products of the citric acid cycle, and accumulation of these molecules signals to the enzymes that there is no need for further energy production. This results in a feedback inhibition of the cycle to prevent excess buildup of these molecules. ADP, on the other hand, signals to the enzymes that there is a need for more energy production and therefore does not inhibit the cycle. FADH and vitamin B12 do not directly regulate the enzymes of the citric acid cycle.
