Webmyosin: [noun] a fibrous globulin of muscle that can split ATP and that reacts with actin in muscle contraction to form actomyosin. WebAs actin is pulled, the filaments move approximately 10 nm toward the M-line. This movement is called the power stroke, as movement of the thin filament occurs at this step (Figure 9.3. 3c). In the absence of ATP, the myosin head will not detach from actin.

WebThe most widely accepted theory explaining how muscle fibers contract is called the sliding filament theory. According to this theory, myosin filaments use energy from ATP to “walk” along the actin filaments with their cross bridges. … WebThe enzyme at the binding site on myosin is called ATPase. The energy released during ATP hydrolysis changes the angle of the myosin head into a “cocked” position. The myosin head is then in a position for further movement, possessing …
