Answer 2

There are various significance of respiration. It helps the body in below way:

cellular respiration is important because it provides the energy for living organisms to perform all of the other necessary functions which are needed to  maintain life. Most single-celled organisms, such as bacteria, do not require much energy and are able to survive on glycolysis only and fermentation.

Glucose and oxygen react together in cells to produce CO2 and water and releases energy. Energy is released in the reaction and that helps the body. The mitochondria which is found in the cell cytoplasm, are where most respiration happens.
