Question

question 5 myosin is also known as the: a thin myofilament b thick myofilament c intermediate myofilament d short myofilament e sarcomere

Explanation:

Myosin is a motor protein that plays a crucial role in muscle contraction. In muscle fibers, myofilaments are the contractile elements. Actin is the thin myofilament, while myosin is the thick myofilament. The interaction between actin (thin) and myosin (thick) myofilaments is what drives muscle contraction. Sarcomere is the basic unit of a muscle's striated muscle tissue. Intermediate and short myofilaments are not the standard terms for myosin.

Answer:

B. thick myofilament
