| Cellular Respiration | Process of coverting food into a usable source of energy. |
| ATP | The form of energy used to fuel cellular reactions. |
| Composed of an adenosine molecule connected to 3 phosphate groups. | ATP |
| Composed of an adenosine molecule connected to 2 phosphate groups. | ADP |
| Place where energy is stored within the ATP molecules. | Between the 2 and 3 phosphate groups. |
| Negative | Electrical charge on an electron |
| Positive | Electrical charge on a proton. |
| Aerobic Respiration | Type of cellular respiration that takes place in the presence of oxygen. |
| Anaerobic Respiration | Type of cellular respiration that takes place without oxygen. |
| Produces 2 ATP molecules. | Anaerobic Respiration |
| Produces 36 ATP molecules. | Aerobic Respiration |
| The first stage of both aerobic and anaerobic repspiration. | Glycolysis |
| Glycolysis | Means "sugar splitting." |
| Enzymes | Speeds up chemical reaction rates. |
| Produced in the first stage of glycolysis. | 2 molecules of PGAL |
| PGAL | Phosphoglyceraldehyde |
| 2 molecules of PGAL produces this in the later stage of glycolysis. | 2 molecules of pyruvic acid. |
| A proton. | Hydrogen without its electron. |
| Hydrogen atoms (its electrons) form these substances during glycolysis. | NAD+ and NADH |
| Lose of electrons. | Oxidation |
| Gain of electrons. | Reduction |
