What happens when myosin filaments hydrolyze ATP molecules in muscles?

Question

Quizplus · Accepted Answer

When myosin filaments hydrolyze ATP molecules, they undergo a series of steps that ultimately result in the formation of actin-myosin complexes, which leads to muscle contraction. Specifically, hydrolysis of ATP causes myosin to release from actin, allowing myosin to bind to a new site on actin. This binding triggers a conformational change in myosin, which pulls actin towards the center of the sarcomere and shortens the muscle fiber. The cycle repeats as long as ATP is available and calcium ions are present.
