Q. What is the function of ATP in skeletal muscle contraction ?

A. Hydrolysis of ATP by myosin energizes the cross -bridges, providing the energy for force generation.

B. Binding of ATP to myosin dissociates cross-brodges bound to actin, allowing the bridges to repeat their cycle of activity.

C. Hydrolysis of ATP by the Ca2+-ATP ase in the sarcoplasmic reticulum provides the energy for the active transport of Ca2+ into the reticulum, lowering cytosolic Ca2+ to per-release levels, ending the contraction and allowing the muscle fiber to relax, 

D. All of these
