Question

What is the substance that destroys the muscle protein during rigor mortis
a) proteolytic enzymes
b) mitochondrial enzymes
c) lysosome enzymes
d) esterases

Answer 1

Human body cells contain lysosomes, these are biological enzymes that are used for destroying unwanted substances by digesting it.

Lysosomes can easily digest anything. And thus when a person dies, the cells inside the body bursts and all the contents come out.

This provides liberty to lysosomes to digest the whole body. Rigor mortis ends here because now autolysis begins to take place in the body and the tissues begin to 'soften' as the body starts to decompose. The correct answer is “C” Lysosomes.

Answer 2

The substance that destroys muscle protein during rigor mortis is Lysosome enzymes.

Option: (c)  

Explanation:  

• Lysosome is a cell organelle that is a part of the endomembrane system.  

• They arise from the Golgi apparatus and have a number of acids and enzymes in them which are responsible for the destruction of improper cellular organelles.  

• They, maintain an acidic pH which aids in destruction. The improperly folded proteins and the proteins that are not required by the body is destructed by these lysosomes.
