Q. In skeletal muscle the ATPase activity is shown by which contractile protein?

A
Troponin
B
Tropomyosin
C
Myosin
D
A-actin
Solution:
  • Myosins are a superfamily of motor proteins best known for their roles in muscle contraction.
  • It aids in a wide range of other motility processes in eukaryotes.
    They are ATP-dependent and responsible for actin-based motility. The term was originally used to describe a group of similar ATPases found in the cells of both striated muscle tissue and smooth muscle tissue.
