the experimental data reported indicate that creatine kinases bound to the sarcolemmal membrane and to the membrane of sarcoplasmic reticulum are coupled to na+ , k+-atpase and ca2+-atpase , respectively , and ensure rapid rephosphorylation of adp produced in the atpase reactions , maintaining a high and constant atp : adp ratio near the active centers of atpases .
