AMUAMU 2012Locomotion and Movement
Solution:
Actinis acontractileprotein found in muscle tissue, in which it occurs in the form of filaments called thinfilaments. Eachfilaments 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.
