ATP hydrolysis (ATP -> ADP + Pi) at the myosin head is used mainly to:

hard

APull actin inward during the power stroke

BDetach myosin from actin

Re-cock (energize) the myosin head into a high-energy position

DBind Ca2+ to troponin

ECreate acetylcholine in the motor neuron

Explanation

Hydrolysis energizes the myosin head (cocking). ATP binding detaches myosin; then hydrolysis repositions it, ready for the next cycle.
