What are the two proteins responsible for the striated appearance of myofibrils?

Options

  1. AMyosin and Elasticin
  2. BZ-line and Elasticin
  3. CActin and Myosin
  4. DThin filaments and Thick filaments

Correct answer

C. Actin and Myosin

Step-by-step solution

.Skeletal muscles are known as voluntary muscles because their activities are under the voluntary control of the nervous system. The striated appearance of myofibrils is due to the distribution pattern of two important proteins - Actin and Myosin. The light bands contain actin and the dark bands contain myosin. The light bands in a myofibril contain actin and is called I-band or Isotropic band.
