effective functional compartmentation of atp could result from the binding of creatine kinase to cellular organelles ( e.g. , myofibrils and mitochondria ) such that high energy charge at the myofibrils is maintained by the reverse creatine kinase reaction , while phosphocreatine is synthesized mainly at the mitochondria in the forward creatine kinase reaction .
