Metabolic enzymes are the most active for human cells. The reason for this is because they regulate each biochemical reaction. Metabolic enzymes are the most active for human cells. The reason for this is because they regulate each biochemical reaction.
Phosphofructokinase (PFK) is an important enzyme in virtually all living cells. It performs the committed step in the glycolytic pathway, namely, the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate.Glycolysis is a pathway that uses glucose to maintain a steady amount of ATP, the major energy carrier in living cells.Phosphofructokinase is a multisubunit protein. In such proteins, the subunits may behave cooperatively; that is, the activity of one subunit influences the activity of all the other subunits.n especially notable example of an allosteric protein is hemoglobin, which is an oxygen-transport protein rather than an enzyme. The activity of an allosteric enzyme such as PFK can be regulated by the binding of a small molecule that acts as an activator or inhibitor.
