WebThe binding of the myosin heads to the muscle actin is a highly regulated process. When a muscle is resting, actin and myosin are separated. To keep actin from binding to the active site on myosin, regulatory proteins block the molecular binding sites. These regulatory proteins are tropomyosin and troponin. WebOnce the myosin-binding sites are exposed, and if sufficient ATP is present, myosin binds to actin to begin cross-bridge cycling. Then the sarcomere shortens and the muscle …
