WebMay 12, 2024 · Sources of ATP. ATP 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 direct source of energy for mus-cle contraction is ATP. ATP, however, is not stored in large amounts in muscle fibers and is depleted in a few seconds. The secondary …

WebJun 8, 2024 · ATP prepares myosin for binding with actin by moving it to a higher- energy state and a “cocked” position. Once the myosin forms a cross-bridge with actin, the Pi disassociates and the myosin undergoes the power stroke, reaching a lower energy state when the sarcomere shortens. WebJul 30, 2024 · As the ATP produced by creatine phosphate is depleted, muscles turn to glycolysis as an ATP source. Glycolysis is an anaerobic (non-oxygen-dependent) …
