(C) Myosin is a thick filament which is also a polymerized protein
(D) The globular head of mermyosin consists of light meromyosin (LMM)
Of the above statements

A

(A), (B) and (C) are correct

B

(A), (B) and (D) are correct

C

(A) and (C) are correct

D

(B) and (D) are correct

Text Solution

Verified by Experts

The correct Answer is:
C
* The main component of thin filament is the protein actin. Two actin molecules join to form actin filament that is twisted into a helix. Each of this is called filamentous F-actin.
* The complex protein tropomyosin is distributed at regular intervals on the actin filament.
* Myosin is the main component of thick filament. A myosin filament is a polymer consisting of 300 myosin monomers.
* The globular head of meromyosin consists of heavy meromyosin. Refer in Book
