| cellular respiration | The process where cells convert food into energy for metabolic processes. |
| electron transport | The third step in cellular respiration; the process whereby cells convert energy into ATP that can then be used by the cells to run metabolic processes. |
| Glycolysis | The first step in cellular respiration whereby carbon molecules (food) is converted into energy by the cell. |
| Krebs cycle | The second step in cellular respiration whereby carbon molecules are converted into ATP, water and CO2. |
| Photosynthesis | Plants form carbohydrate molecules that the cell can later use as an energy source from CO2, sunlight and water. |
| metabolism | the chemical changes in living cells by which energy is provided for vital processes and activities and new material is assimilated |
| ATP | adenosine 5 triphosphate |
| enzymes | proteins made by the cell that help the cell break bonds in the food molecules to make energy for cellular growth and reproduction |
