Question

During resting stage the binding site of action of myosin remains masked by

• A. Troponin
• B. Gactin
• C. Tropomyosin
• D. Meromyosin

Answer 1

Answer: (C)

Tropomyosin

• The resting stage is also called interphase. The interval in the cell cycle between two cell divisions when the individuals cannot be distinguished, the interphase goes through the resting stage.
• A subunit of troponin called tropomyosin is masked during the resting stage binds myosin on the actin filaments.

So, the correct option is 'Tropomyosin'.
