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.”.
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.
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.
Aug 20, 2019 · Respiration is the process of gas exchange between the air and an organism's cells. Three types of respiration include internal, external, and cellular respiration. External respiration is the breathing process. It involves inhalation and exhalation of gases. Internal respiration involves gas exchange between the blood and body cells.
Jan 15, 2021 · Cellular respiration is the process through which cells convert fuel into energy and nutrients. To create ATP and other forms of energy that they can use to power their life functions, cells require fuel and an electron acceptor which drives the chemical process of turning energy from that fuel into a useable form.
6 days ago · 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 the process by which biological fuels are oxidized in the presence of an inorganic electron acceptor, such as oxygen, to drive the bulk production of adenosine triphosphate (ATP), which contains energy.

Review your understanding of cellular respiration in this free article aligned to NGSS standards. Key points: Cellular respiration is a process that happens inside an organism’s cells.
The respiratory system. The process of physiological respiration includes two major parts: external respiration and internal respiration. External respiration, also known as breathing, involves both bringing air into the lungs (inhalation) and releasing air to the atmosphere (exhalation).
