Which of the labelled parts on the graph represents rigor mortis ?

Locomotion and Movement

Solution:

Rigor mortis is the rigidity that develops in dying muscles as $ATP$ becomes depleted and cross-bridges remain attached. Rigor mortis can be relieved only by removal of $Ca^{2+}$ and addition of $ATP$.
