Quizplus · Accepted Answer

Calcium ions are the final chemical messenger and "trigger" for muscle contraction. They bind to troponin, which leads to the movement of tropomyosin and exposes the binding sites on actin for the myosin heads to attach and initiate muscle contraction. Sodium ions and acetylcholine are involved in the transmission of the nerve impulse to the muscle fiber, while acetylcholinesterase breaks down acetylcholine to end the nerve impulse. Creatine phosphate is a high-energy storage molecule used to rapidly produce ATP during intense exercise.
