Question

62-The main function of tropomyosin in skeletal muscles include
(A) Sliding on actin to detach from Z line
(B) Releasing Ca2+ after initiation of contraction
(C) Act as regulatory protein along with troponin
(D) Act as neurotransmitter receptor

Answer 1

Answer:

C - Tropomysin and troponin are regulatory protein

Answer 2

• Tropomyosins belong to the class of contractile proteins, which work together with proteins like actin and myosin.
• The function of such proteins is to regulate the contraction of both muscles as well as non-muscle cells.
• Tropomyosin is a rod-shaped protein. It is wrapped around the actin protein.

The main function of tropomyosin in skeletal muscles includes sliding on actin to detach from the Z line.

Hence the correct option is (A)  Sliding on actin to detach from the Z line.
