Final answer:

ATP is the primary energy source for muscle contraction, supported by various molecules like creatine phosphate, glucose, glycogen, and pyruvate.


Explanation:

ATP (adenosine triphosphate) is the immediate source of energy for muscle contraction. Muscle fibers initially use ATP stored in the cell and then rely on sources like creatine phosphate, glucose, glycogen, and pyruvate to replenish ATP levels for continued muscle movement. ATP's role in muscle contraction is crucial for the release and movement of the myosin head along actin filaments.
