Q. Arrange the given steps of muscle contraction in the series of events from first to last.
I. Myosin head binds to the exposed active site on actin to form a cross-bridge.
II. The $Z$-line attached to these actins are also pulled inwards thereby, causing shortening of sarcomere, also called contraction.
III. This pulls the attached actin filaments towards the centre of $A$-band.
The correct option is

Locomotion and Movement

Solution:

Correct answer is (c) $I \rightarrow III \rightarrow II$
