Answer 1

Answer:

Hydrolysis of ATP

Explanation:

The biochemical basis of rigor mortis in terms of the interaction between actin and myosin can be explained as the condition in which the muscle becomes arrested as ATP is unable to get hydrolyzed and this is basically the energy source that is needed for movement. Myosin head molecules becomes glued to actin filaments and the muscles become rigid in the absence of ATP. This condition peaks at 13 hours and then dissipates after 48 hours.
