Answer 1

1. **ATP** is a molecule that carries energy inside cells and serves as the energy currency of a cell. The 2. **Chloroplast** is the organelle in plant cells where photosynthesis occurs. During photosynthesis, 3. **Chlorophyll** captures energy from sunlight. The 4. **Light-dependent reactions** is a series of reactions that convert light energy into chemical energy, producing NADPH and ATP. 5. **ADP** is a lower energy molecule that can be converted to ATP by adding a third phosphate group. The 6. **Electron transport chain** is a system that moves high-energy electrons and pumps hydrogen ions during photosynthesis. The 7. **Light-independent reactions** consists of reactions that do not require light and convert carbon dioxide into glucose. In the chloroplast, the 8. **Stroma** is the fluid-filled space where light-independent reactions take place. 9. **ATP** is created from ADP during the light-dependent reactions. 10. **Photosystem II** is the protein complex where NADP+ is converted to NADPH. The 11. **Photosystem II** is where water is split, producing oxygen and creating hydrogen ions. 12. **Thylakoid** are sack-like structures in chloroplasts where light-dependent reactions occur. 13. **Photosynthesis** is the process that transforms light energy into stored chemical energy. 14. **NADP+** is the electron carrier molecule that accepts two high-energy electrons and a hydrogen ion to become NADPH.

(Note: There seems to be a repetition in numbers 10 and 11, as both describe functionally related parts of the light-dependent reactions involving water splitting. "Photosystem II" is used twice; the distinction lies in their roles within the process.)
