Question

Why do muscles contain contractile protiens?

Answer 1

HELLO FRIEND HERE IS UR ANSWER ☺️☺️☺️

Three types of proteins form myofibrils: contractile, regulatory, and structural. Contractile proteins generate force for muscle contraction.

here's your answer!!☺☺

Contractile proteins generate force for muscle contraction...
The two contractile proteins found in muscles are actin and myosin..
Actin is the thin filament and myosin is the thick one...
The thin filaments extend from the Z lines; they are formed by the actin molecules twisted in a helix. Each molecule has a myosin-binding site for the myosin head.....

These muscles show contraction and relaxation and hence allowing smooth movent of our body..
