Phosphofructose kinase
WebApr 28, 2010 · Phosphofructokinase is the most important rate-controlling enzyme required for glycolysis, the metabolic pathway that coverts glucose into pyruvate, thereby releasing energy to be used for a variety of functions such as maintaining the shape of red blood cells. WebAt the Kinase, Hexkinase, Phosphofructose Kinase, and Pyruvate Kinase. Why does glycolysis need to be regulated? Because the principle function of glycolysis is to produce ATP, it must be regulated so that ATP is generated only when needed. What determines the level of pyruvate in a cell?
