Assertion : A primary myofilament is made of rod like molecules of protein myosin. Reason : Actin and myosin form contractile apparatus.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.
Explanation:
Large number of filaments are arranged parallelly and are called myofilament (myofibril). Myofibrils have alternate dark and light bands. Actin and myosin are contractile proteins responsible for contraction of muscles.

Which out of the following represent collagenous connective tissue
1 A - Sarcolemma
2 B - Fascicle
3 A - Fascicle
4 B - Sarcolemma

The light and dark regions of myofibril are called
1 A-band and I-band, respectively
2 Z-band and M-band, respectively
3 I-band and A-band, respectively
4 A-band and M-band, respectively
Explanation:
A detailed study of the myofibril has established that the striated appearance is due to the distribution pattern of two important proteins - Actin and Myosin. The light bands contain actin and is called I-band or Isotropic band, whereas the dark band called ' A ' or Anisotropic band contains myosin.
