It's not C
@Michele_Laino
im 90% sure its B
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
i think B is correct
