The contractile protein of skeletal muscle involving ATPase activity is

  1. troponin
  2. tropomyosin
  3. myosin
  4. -actinin.

Answer

(3) myosin

Solution

As per NCERT, the globular head of meromyosin (myosin) is an active ATPase enzyme and has binding sites for ATP and active sites for actin.

Myosin hydrolyses ATP and uses the energy for cross-bridge formation and muscle contraction.

Troponin and tropomyosin are regulatory proteins of the thin filament.
