Question

The molecule that is the independent force-generator in muscle fibers is:

a. troponin
b. tropomyosin
c. actin
d. myosin

Answer 1

The correct option is : d. myosin

Step-by-step explanation:

Myosins are the ATP dependent motor proteins that are involved in contraction and movement of the muscles in the eukaryotes. The myosins are called a superfamily of the motor proteins, as they are present in abundance in the muscle fibers.

Myosins acts as the independent force-generator in the muscle fibers.
