Aug 6, 2021 · Respiration Definition. “Respiration is defined as a metabolic process wherein, the living cells of an organism obtains energy (in the form of ATP) by taking in oxygen and liberating carbon dioxide from the oxidation of complex organic substances.”.
From plants and animals to prokaryotic bacteria, archaeans, eukaryotic protists, fungi, and animals, all living organisms undergo respiration. During normal human respiration, glucose reacts with oxygen to produce the energy needed for growth, repair and movement.
In physiology, respiration is the movement of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction to the surrounding environment.
Respiration is the process through which living organisms take in oxygen and give out carbon dioxide to release energy. So, naturally, respiration is a major and vital process of gas exchange.
Aug 20, 2019 · Respiration is the process in which gas is exchanged between organisms and their habitat. Common types include external, internal, and cell respiration.
Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water. It includes glycolysis, the TCA cycle, and oxidative phosphorylation.
Cellular respiration is a process that happens inside an organism’s cells. This process releases energy that can be used by the organism to live and grow.

Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
Cellular respiration is a vital process that occurs in the cells of all living organisms. [2] [better source needed] Respiration can be either aerobic, requiring oxygen, or anaerobic; some organisms can switch between aerobic and anaerobic respiration. [3] [better source needed]
