In a photosystem:
| 1. | The reaction centre is where light is captured, while the antenna complex is where this light energy is transformed into chemical energy. |
| 2. | The antenna complex is where light is captured, while the reaction centre is where this light energy is transformed into chemical energy. |
| 3. | The antenna complex is where light energy is captured and transformed into chemical energy. |
| 4. | The reaction centre is where light energy is captured and transformed into chemical energy. |
| I: | Water splitting complex is associated with PSII in photosynthetic plants. |
| II: | Chlorophyll a reaction center in PSII is called as P680 |
