| A | B |
| Aerobes | Use of oxygen to break down glucose. |
| Anaerobes | Do not use oxygen to break down glucose. |
| Autotrophs | Can produce their own food. |
| Biochemical Pathways | A series chemical reactions that create energy for an organism. |
| Calvin Cycle | Second stage of photosynthesis produces a sugar and adds back to the cycle. |
| Cell Respiration | The process of breaking down sugars for energy. |
| Chemoautotrophs | Bacteria that are able to produce their own food through chemical decay. |
| Chlorophyll | Major component of chloroplasts and gives leaves color. |
| Energy | The ability to do work. |
| Fermentation | Anaerobic respiration. |
| Food Chain | Movement of energy though the eating of different organisms |
| Glycolysis | The breaking down of sugars. 2ATP and 2 pyruvate |
| Hetrotrophs | Feed on other animals. |
| Light Reactions | The first stage of photosynthesis H2O is broken down. |
| Oxidation | A substance that loses electrons. |
| Photorespiration | Plant produces one three carbon phosphate and one two carbon molecule that breaks down into CO2. |
| Photosynthesis | The use of light to create carbon compounds. |
| Pigment | Any colored substance that does not dissolve in water. |
| Pyruvate | Three-carbon molecule as a result from Glycolysis. |
| Reduction | A substance gains in electrons. |
