Which of the following explains why ATP hydrolysis to ADP + Pi provides energy for muscle contraction?

Breaking the high-energy phosphate bond lowers the free energy of the system and the released energy drives conformational changes in contractile proteins.

ATP hydrolysis increases cellular pH dramatically, which stimulates all muscle enzymes to work faster and therefore produces contraction without additional chemical work.

The released inorganic phosphate binds irreversibly to myosin forming a permanent cross-bridge that maintains contraction until the phosphate is depleted.

Hydrolysis of ATP converts it into glycogen directly, which is then oxidized to provide heat that makes muscles contract more effectively during exercise.
