Actin filament is made up of

Options

(a) Actin, troponin and tropomyosin
(b) Actin, troponin
(c) Myosin, troponin
(d) Actin, tropomyosin

Correct Answer:

Actin, troponin and tropomyosin

Explanation:

One thin filament probably contains 300-400 actin molecules abount 50 tropomyosin and 50 troponin. It is said that tropomyosin plays a vital role in sensitizing the contractile proteins (actin and myosin) to calcium ions.
