| Term | Definition |

| cellular respiration | process that releases energy from food in the presence of oxygen |
| aerobic | process that requires oxygen |
| anaerobic | process that does not require oxygen |
| glycolysis | first set of reactions in cellular respiration during which a molecule of glucose (a 6-carbon compound) is broken into 2 molecules of pyruvic acid (a 3-carbon compound) |
| nad+ | electron carrier involved in glycolysis |
| Krebs cycle | second stage of cellular respiration in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions |
| matrix | innermost compartment of the mitochondrion |
| fermentation | process by which cells release energy in the absence of oxygen |
