A low NADH to NAD⁺ ratio would activate which enzyme in the citrate cycle? A) succinyl-CoA synthetase B) fumarase C) citrate synthase D) succinate dehydrogenase

Question

Quizplus · Accepted Answer

A low NADH to NAD+ ratio signifies a low level of energy in the cell, and the citrate cycle needs to be activated to increase ATP production. Citrate synthase is the enzyme that initiates the citrate cycle, and when it is activated, it triggers the rest of the cycle. The other enzymes listed are not directly influenced by the NADH to NAD+ ratio.
