ATPase enzyme needed for muscle contraction is located in:
ATPase enzyme needed for muscle contraction is located in:
actinin
troponin
myosin
actin.
Solution
During muscle contraction, hydrolysis of ATP into ADP and inorganic phosphate occurs. The energy released during the process raises the meromyosin head to a high-energy state. The enzyme myosin ATPase catalyses the reaction in the presence of \(\mathrm{Ca}^{2+}\) and \(\mathrm{Mg}^{2+}\).
\(\mathrm{ATP} \underset{\mathrm{Ca}^{+2}, \mathrm{Mg}^{+2}}{\stackrel{\text { Mysin ATPase }}{\rightleftarrows}} \mathrm{ADP}+\mathrm{Pi}+\) Energy
