cellular respiration
Mitochondrial energy production
Cellular respiration is the biochemical process by which cells convert nutrients, primarily glucose, into usable energy in the form of ATP.
This metabolic process occurs in the mitochondria of eukaryotic cells and involves multiple stages: glycolysis, the citric acid cycle, and the electron transport chain.
Oxygen is typically required for the most efficient energy extraction, which is why we breathe.
Plants perform cellular respiration just like animals do, though they also photosynthesize.
