| cellular respiration | the enzyme controlled process by which energy is released from food molecules |
| ATP | adenosine triphosphate, energy transfer compoiund in cells |
| ADP | the lower-energy compound remaining after one phosphate group is removed from ATP |
| anaerobic respiration | process by which ATP is produced from glucose without the use of oygen molecules; makes 4 ATP 's but yields a net gain of 2 ATP molecules |
| aerobic respiration | method of producing ATP form the complete oxidation of glucose which produces carbon dioxide and water; makes 38 ATP's but yields a net gain of 36 |
| glycolysis | the process of breaking down the glucose molecule is broken down without the use of oxygen |
| fermentation | the process by which glucose is broken down without oxygen into pyruvic acid and then into alcohol and carbon dioxide |
| Krebs Cycle | also called Citric Acid cycle, part of aerobic respiration |
| Electron transport chain | a series of oxidation-reduction reactions in which most of the energy produced from the breakdown of glucose is transferred to ATP |
| oxygen debt | the amount of oxygen needed to get rid of lactic acid |
| oxidation | a reaction in which an atom or molecule loses electrons and therefore takes on a positive charge |
| reduction | a reaction in which an atom or molecule gains electrons and therefore takes on a negative charge |
| acetyl CoA | a compound produced during pyruvic acid breakdown by the combination of an acetyl group with coenzyme A |
