- 1. relating to, involving, or requiring an absence of free oxygen.
- 2. the sequence of reactions by which most living cells generate energy during the process of aerobic respiration. It takes place in the mitochondria, consuming oxygen, producing carbon dioxide and water as waste products, and converting ADP to energy-rich ATP.
- 3. the breakdown of glucose by enzymes, releasing energy and pyruvic acid.
- 5. an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae).
