Which of the following is involved in the process of muscle relaxation

Question

Quizplus · Accepted Answer

Acetylcholinesterase breaks down acetylcholine, which stops the muscle contraction by allowing the muscle membrane to return to its resting potential. Additionally, Ca2+ ions are actively taken up by the lateral sacs of the sarcoplasmic reticulum when there is no longer a local action potential, which also contributes to muscle relaxation. Therefore, both option (a) and (b) are involved in the process of muscle relaxation. Option (c) is incorrect because cross-bridge detachment is involved in muscle relaxation, but not by bending the filaments to their resting position.
