WebResting muscles store energy from ATP in the myosin heads while they wait for another contraction. Figure 1. The cross-bridge muscle contraction cycle, which is triggered by Ca 2+ binding to the actin active site, is shown. With … WebThe muscle fiber will repolarize, which closes the gates in the SR where Ca ++ was being released. ATP-driven pumps will move Ca ++ out of the sarcoplasm back into the SR. This results in the “reshielding” of the actin-binding sites on the thin filaments.
