Answer 8

These are the stages of muscle contraction

Three functions of ATP in muscle contraction are the following: (1) Its hydrolysis by an ATPase activates the myosin head so it can bind to actin and rotate; (2) Its binding to myosin causes detachment from actin after the power stroke; and (3) It powers the pumps that transport calcium ions from the cytosol back into the sarcoplasmic reticulum.

it includes both myosin and actin
