Explanation:
Detailed explanation-1: -Calcium is the essential for the muscle contraction as release of calcium ions from sarcoplasmic reticulum trigger the muscle contraction.
Detailed explanation-2: -Both calcium & magnesium are required for muscle contraction. Calcium binds to troponin which exposes the active sites on actin. Now myosin head can bind the active sites on actin, initiating the process of muscle contraction. The hydrolysis of ATP is used to provide energy for muscle contraction.
Detailed explanation-3: -Which of the following is not required for muscle contraction? Nervous tissue stimulus is not required for muscle to contract.
