WebATP supplies the energy for muscle contraction to take place. In addition to its direct role in the cross-bridge cycle, ATP also provides the energy for the active-transport Ca ++ pumps in the SR. Muscle contraction does not occur without sufficient amounts of ATP. WebThe source of energy that is used to power the movement of contraction in working muscles is adenosine triphosphate (ATP) – the body’s biochemical way to store and transport energy. However, ATP is not stored to a great extent in cells. So once muscle contraction starts, the making of more ATP must start quickly. WebJan 24, 2014 · ATP is supplied via three separate sources: creatine phosphate, the glycolysis-lactic acid system, and aerobic metabolism or oxidative phosphorylation. THE … honey stoner
