| A: | Light reactions [‘Photochemical’ phase] include light absorption, water splitting, oxygen release, and the formation of high-energy chemical intermediates, ATP and NADPH. |
| B: | The photosynthetic pigments are organised into two discrete photochemical light harvesting complexes (LHC) within the Photosystem I (PS I) and Photosystem II (PS II). |
| C: | Each photosystem has only chlorophyll a forming a light harvesting system also called antennae. |
| D: | In PS II the reaction centre chlorophyll a has an absorption peak at 700 nm, and is called P700. |

1. Only A, B and C
2. Only A, C and D
3. Only B, C, and D
4. A, B, C and D
| A: | In photosynthetic bacteria, the proteins that gather light for photosynthesis are embedded in cell membranes. |
| B: | Chloroplasts may be photosynthetic bacteria that adapted to life inside plant cells. |
| C: | In the reaction: 2 H2O + 2 A + (light, chloroplasts) → 2 AH2 + O2 ; A is the electron acceptor. |
| D: | Phosphoglycolate produced during photorespiration cannot be metabolized by the CalvinBenson cycle and represents carbon lost from the cycle. |
