$Ca^{2+}$ and $Mg^{2+}$

Vedclass · Answer

(A) $Ca^{2+}$ and $Mg^{2+}$ ions are essential for muscle contraction.$Ca^{2+}$ ions bind to troponin, which exposes the active sites on actin filaments for myosin head attachment.$Mg^{2+}$ ions act as a cofactor for the enzyme myosin ATPase, which is required for the hydrolysis of $ATP$ to provide energy for the contraction process.Reaction: $	ext{ATP} + H_{2}O \xrightarrow{Mg^{2+}/Ca^{2+}} 	ext{ADP} + P_{i} + 	ext{Energy}$.
