Question

ATPase enzyme needed for muscle contraction is located in - (A) Troponin (B) Myosin (C) Actin (D) Actinin

Tardigrade Admin · Accepted Answer

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