Myosin II binding to and subsequent dissociation from actin in muscle contraction is due to

Question

Quizplus · Accepted Answer

The process of muscle contraction involves myosin II binding to actin, which is driven by a conformational change in the myosin head (A) and ATP hydrolysis followed by the release of phosphate within the myosin head (B). These events facilitate the power stroke that pulls the actin filaments past the myosin, leading to muscle contraction.
