Question

Quizplus · Accepted Answer

There are 3 enzymes in glycolysis that serve as control points or regulatory steps. These are hexokinase/glucokinase, phosphofructokinase, and pyruvate kinase. These enzymes catalyze the reactions that are essentially irreversible under cellular conditions, and their activities are regulated by various means, making them key points of control in the glycolytic pathway.
