A decrease in pH inhibits PFK; therefore, decreases the rate of:______________________:

Question

Quizplus · Accepted Answer

A decrease in pH inhibits PFK, which is a key enzyme in the anaerobic glycolysis pathway. Therefore, the rate of anaerobic glycolysis is decreased when the pH decreases. Option A is incorrect because phosphocreatine synthesis does not involve PFK enzyme. Option B is incorrect because aerobic metabolism relies on oxidative phosphorylation and the electron transport chain, which are not affected by PFK inhibition.

A Decrease in PH Inhibits PFK; Therefore, Decreases the Rate
