Final answer:

To relax a muscle, a nerve initiates an action potential, the neurotransmitter is degraded, and the calcium concentration decreases.


Explanation:

The process that must occur for a muscle to be able to relax is:

  1. A nerve must initiate an action potential in the muscle fiber.
  2. The neurotransmitter acetylcholine (ACh) must be degraded by the enzyme acetylcholinesterase.
  3. The calcium concentration in the myofibril must decrease as it is reabsorbed by the sarcoplasmic reticulum.
