Question

which part of mucles protine takes part in work​

Answer 1

Answer:

Troponin and tropomyosin

Explanation:

Actin and myosin are the contractile proteins, and they interact with each other, causing contraction, while troponin and tropomyosin are regulatory proteins that regulate the interaction between actin and myosin.

Myofilaments(actin and myosin) are packed in functional units of striated muscle referred to as sarcomeres.

Hence, Troponin and tropomyosin are the regulatory protein in muscle contraction.

So, the correct answer is 'Troponin and tropomyosin'.
