Summary Introduction
Introduction:
Phosphofructokinase is a catalytic enzyme that plays a crucial role in controlling biochemical process. It plays an important role during glycolysis, in converting fructose-6-phosphate into fructose 1,6-biphosphate. It also converts ATP (adenosine triphosphate) into ADP (adenosine diphosphate) molecules. These steps help in controlling the glycolytic pathway.
