| Question | Answer |
|---|---|
| Adenosine Triphosphate (ATP) | Made up of adenine, ribose, and 3 phosphate groups. Energy storing molecule. |
| Heterotroph | A consumer. Needs to eat to get energy. |
| Autotrophs | Produce energy through many anabolic pathways. |
| Photosynthesis | Anabolic pathway used by plants that involves using sunlight to make energy. |
| Thylakoids | A baglike photosynthetic membrane found in chloroplasts. Arranged in stacks called grana. |
| Stroma | The liquid-filled space surrounding the thylakoids in chloroplasts. |
| NADP+ | One of the molecules that accepts high-energy electrons from chlorophyll and carries them to other molecules during photosynthesis. |
| Light-Dependent Reaction | A reaction of photosynthesis that uses light energy to make ATP and NADPH. |
| Light-Independent Reaction | A reaction of photosynthesis that uses ATP, NADPH, and carbon dioxide to make high-energy molecules |
| Photosystems | Light-collecting units of the chloroplasts. |
| Electron Transport Chain | A series of proteins in which high-energy electrons are used to change ADP to ATP. |
| C4 plants | Pathways use extra ATP to work, but can still carry out photosynthesis even when it's hot. Example: Corn |
| C3 plants | Cannot carry out photosynthesis in hot weather. Example: Rice |
| CAM plants | Save water by taking in carbon dioxide at night. Turn CO2 into acids during night; during day acids turned back into CO2. Example: Pineapple trees |
| Ferrodoxin | Iron-Sulfur protein that mediate transfer of electrons in metabolic pathways, |
| Calvin Cycle | Light-independent reaction used for carbon fixation. |
| Carotenoid | A light-collecting pigment. |
| G3P | A 3-carbon intermediate molecule used to transfer energy in the Calvin Cycle. |
| Chlorophyll | A light-collecting pigment. |
| RuBP | Energy transferring molecule used in Calvin Cycle. |
| Chemiosmosis | Anabolic pathway using chemical energy, instead of light, to produce sugars. |
| Chlorplasts | Organelle where photosynthesis occurs. |
