Why Is Cellular Respiration Important For Living Organisms?

Cellular respiration is vital not just to man but also to most living organisms. It provides them with the essential energy to perform work, everyday tasks and all bodily functions. Thus in essence, Cellular respiration is responsible for sustaining and maintaining life itself.

Cellular respiration takes place within the cells and tissues of an organism and occurs in gradual steps. It is a series of metabolic processes that allow the oxidation of energy-rich glucose. The energy obtained through this process, can then be used by the body. The waste products are carbon dioxide and water (vapor). They are then absorbed by the blood and taken to the lungs where they are exhaled out of the body. They may also pass out through sweat and urine.

Most bacteria and single-celled organisms do not require much energy and therefore do not require cellular respiration.
