WebJan 19, 2024 · Myosin molecules interact with actin filaments, a component of the cytoskeleton. When bound to actin, myosin uses energy from ATP to pull on actin and cause a muscle contraction. Myosin... WebThe first step in the process of contraction is for Ca ++ to bind to troponin so that tropomyosin can slide away from the binding sites on the actin strands. This allows the myosin heads to bind to these exposed binding sites and form cross-bridges. WebHow does actin and myosin work? Myosin binds to actin at a binding site on the globular actin protein. Myosin has another binding site for ATP at which enzymatic activity hydrolyzes ATP to ADP, releasing an inorganic phosphate molecule and energy. ATP binding causes myosin to release actin, allowing actin and myosin to detach from each other. great learning wordpress
