| Question | Answer |
|---|---|
| Autotrophs | An organism that produces its own nutrients from inorganic substances or from the environment |
| Heterotrophs | An organism that obtains organic food molecules by eating other organisms or their by products and that cannot synthesize organic compounds from inorganic materials |
| Photosynthesis | The conversion of light energy from the sun into chemical energy in the form of organic compounds |
| Light reaction | The first set of reactions in photosynthesis which are triggered by the absorption of light and produced NADPH and ATP to be used in the Calvin cycle |
| Chloroplast | Organelles found in the cells of plants and algae |
| Thylakoid | Membrane system of sacs found in chloroplasts that contain cholorophll and are the site of the light reaction in photosynthesis |
| Stroma | The solution that surrounds the thylakoids in a chloroplast, in plants |
| Chlorophyll | A green pigment that is present in most plant cells, that gives plants their green color, reacts with sunlight , carbon dioxide, and water to form carbohydrates |
| Cellular respiration | The process by which cells obtain energy from carbohydrates |
| Carbon fixation | The synthesis of organic compounds from carbon dioxide such as in photosynthesis |
| Calvin cycle | A biochemical pathway of photosynthesis in which carbon dioxide is converted to the 3-carbon sugar glyceraldehyde-3phosphate which can ultimately be used to form glucose |
| Stomata | Small pores usually on the underside of leaves that allow gases and water to enter or leave a plant |
| C3 plants | Plants that use the Calvin cycle after the light reaction in photosynthesis |
| C4 plants | Plants that use the C4 pathway which is a process in which carbon dioxide is bound to a compound to form a four carbon intermediate |
| CAM plants | Plants that use the CAM pathway in which CAM plants take in carbon at night and fix it into various organic compounds and release it during the day (into the Calvin cycle). |
| Ribulose biphosphate | The 5 carbon sugar with two attached phosphates that bonds with carbon dioxide for carbon fixation in the Calvin cycle |
| 3 PGA | A 3 carbon intermediate in the Calvin Cycle |
| G3P- glyceralderhyde-3-phosphate | The three carbon sugar produced in the Calvin cycle and ultimately used to make carbohydrates for later use |
| NADPH and NADPH+ | The high and low energy forms of a compound for energy transfer in the two stages of photosynthesis. NADPH is produced in the light reaction and then used up in carbon fixation in the Calvin cycle |
