Which of these happen(s) in muscle contraction?
A. Increase in Ca++ concentration level leads to the binding of calcium with a subunit of troponin on actin filaments. and thereby removes the masking of active sites for myosin.
B. During the shortening of the muscle, A-bands get reduced, whereas, the I-bands retain the length.
C. A muscle fibre is a syncytium.
D. Isotropic band of a myofibril consists of myosin.
