Q. Given below are some events which occur during muscle contraction.
(i) ATP is hydrolyzed.
(ii) Myosin heads bind to actin.
(iii) Hemoglobin concentration in muscle fibers increases.
(iv) Calcium concentration in the sarcomere increase.
(v) I bands shorten and H zones disappear.
Select the correct events which occur during muscle contraction.

Locomotion and Movement

Solution:

Events i, ii, iv and v only occurs during muscle contraction. Concentration of myoglobin, red coloured oxygen storing pigment, in muscle fibres increases.
