ATP binding causes the myosin head to detach from the actin (Figure 10.11d). After this occurs, ATP is converted to ADP and P i by the intrinsic ATPase activity of myosin.

WebCa2+ binds to troponin, troponin changes shape and moves tropomyosin away from active sites once the tropomyosin blocked is removed, and myosin head bind to actin. This leads to contraction.

Actin has binding sites for myosin attachment, but strands of tropomyosin block the binding sites and prevent actin-myosin interactions when the muscles are at rest. Tropomyosin is regulated by troponin, which is regulated by calcium (Ca 2+) ions. WebBlocks myosin-binding sites on actin? Tropomyosin Long cylindrical cells? Skeletal muscle fibers Contractile unit?
