ATPase enzyme needed for muscle contraction is located in

Question

ATPase enzyme needed for muscle contraction is located in (A) actinin (B) troponin (C) myosin (D) actin

Tardigrade Admin · Accepted Answer

During muscular contraction myosin cross bridges heads. Myosin is not only an actin binding protein. It is also an ATPase (an enzyme) which is activated by Ca2+ and Mg2+ ions. Hence, ATPase enzyme is located in myosin.

actinin

troponin

myosin

actin

During muscular contraction myosin cross bridges heads. Myosin is not only an actin binding protein. It is also an ATPase (an enzyme) which is activated by $C a^{2 +}$ and $M g^{2 +}$ ions. Hence, ATPase enzyme is located in myosin.
