During high-intensity exercise (e.g., 800 meter run) which enzyme or enzymes are responsible for regulating the anaerobic glycolytic pathway?

Question

Quizplus · Accepted Answer

PFK (phosphofructokinase) is the enzyme responsible for controlling the rate of the anaerobic glycolytic pathway. It catalyzes the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate, a key step in glycolysis. PFK activity is regulated by a number of factors, including ATP levels, AMP levels, and pH. During high-intensity exercise, increased demand for ATP leads to an increase in ADP and AMP levels, which activate PFK and stimulate glycolysis.
