WebApr 16, 2024 · 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.
Respiration (physiology) - Wikipedia
WebIn 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.
Cellular respiration (article) | Khan Academy
WebCellular 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. Many food molecules are broken down into glucose, a simple sugar. Glucose is used in cellular respiration. Glucose and oxygen are inputs of cellular respiration.
