Quizplus · Accepted Answer

The NADH to NAD+ ratio is a measure of the amount of energy being produced in the cell. The citrate cycle is regulated by feedback inhibition, which occurs when the end product of a pathway inhibits an enzyme earlier in the pathway. In this case, when the NADH to NAD+ ratio is high (indicating high energy production), the citrate cycle is inhibited to prevent excess energy production. This is an example of product inhibition.
