Options
(a) actin and myosin
(b) tropomyosin
(c) troponin
(d) all of these
Correct Answer:
all of these
Explanation:
Actin is a contractile protein found in muscle tissue, in which it occurs in the form of filaments called thin filaments. Each filaments consists of two chains of globular actin molecules, around which is twisted a strand of tropomyosin and interspersed troponin. Units of muscle fibre consist of actin and myosin filaments, which interact to bring about muscle contraction.
