Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	myofibril
B	fascicle
C	sarcomere
D	myofilament

Explanation:

Detailed explanation-1: -The myofilament contractile proteins consist of thick filament myosin and thin filament actin proteins. Bound to actin are a complex of regulatory proteins, which include tropomyosin and troponin-T, C, and I.

Detailed explanation-2: -The myofibrils are made up of thick and thin myofilaments, which help give the muscle its striped appearance. The thick filaments are composed of myosin, and the thin filaments are predominantly actin, along with two other muscle proteins, tropomyosin and troponin.

Detailed explanation-3: -The contractile proteins are myosin, the principal component of thick myofilaments, and actin, which is the principal component of thin myofilaments.
