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.
Learn how glucose is broken down into carbon dioxide and water in four stages of cellular respiration: glycolysis, pyruvate oxidation, citric acid cycle, and oxidative phosphorylation. See diagrams, examples, and questions to test your understanding of this metabolic pathway.

Learn how cells extract energy from fuel molecules through cellular respiration, a series of metabolic pathways. Explore the steps, variations, and regulation of this process with videos, articles, and exercises.
Cellular respiration is the process by which individual cells break down food molecules, such as glucose and release energy. The process is similar to burning, although it doesn’t produce light or intense heat as a campfire does.
