Aerobic respiration
Definition
Aerobic respiration is a metabolic process in which cells convert glucose and oxygen into energy, carbon dioxide, and water. It is the primary method of producing ATP in cells.
5 Must Know Facts For Your Next Test
- Aerobic respiration occurs in the mitochondria of eukaryotic cells.
- The process includes glycolysis, the Krebs cycle, and oxidative phosphorylation.
- Oxygen acts as the final electron acceptor in the electron transport chain.
- Aerobic respiration produces up to 36-38 ATP molecules per glucose molecule.
- The byproducts of aerobic respiration are carbon dioxide and water.

Glycolysis: The first stage of cellular respiration where glucose is broken down into pyruvate, producing a small amount of ATP and NADH.
Krebs Cycle: A series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetate derived from carbohydrates, fats, and proteins.
Oxidative Phosphorylation: The final stage of cellular respiration where ATP is synthesized through the phosphorylation of ADP using energy released by electrons as they are transferred to oxygen.
