in the homogeneous control system composed of hexokinase and glucose as atpase , soluble creatine kinase rapidly rephosphorylated adp produced in the presence of 1 mm atp , but the addition of pyruvate kinase in an increasing amount inhibited the reaction of creatine release from phosphocreatine and symmetrically increased the rate of pyruvate production from phosphoenol pyruvate .
