$Ca$

Vedclass · Answer

(D) Muscle contraction is initiated by the release of calcium ions $(Ca^{2+})$ from the sarcoplasmic reticulum into the sarcoplasm.These $Ca^{2+}$ ions bind to the troponin subunit on the actin filaments.This binding causes a conformational change in the troponin-tropomyosin complex,exposing the active binding sites on the actin filaments for the myosin heads.Therefore,$Ca^{2+}$ is the essential mineral element required for the process of muscle contraction.
