The and photosynthesis pathways are so called because the initial carbon fixation product in them are respectively:
| 1. | pyruvate; malate |
| 2. | malate; pyruvate |
| 3. | 3-phosphoglycerate; oxaloacetic acid |
| 4. | glyceraldehyde 3-phosphate; phospho-enol-pyruvate (PEP) |

The extra ATP required [as compared to NADPH] in Calvin cycle comes from:
| 1. | photosystem II | 2. | photosystem I |

In the given simplified diagram of the Calvin Cycle,
ATP is utilized at points:
1. A and B only
2. A and C only
3. B and C only
4. A, B and C
The chronological order of organelles involved in the photorespiration cycle is:
| 1. | chloroplasts, leaf peroxisomes and mitochondria |
| 2. | chloroplasts, mitochondria and leaf peroxisomes |
| 3. | mitochondria, chloroplasts, and leaf peroxisomes |
| 4. | mitochondria, leaf peroxisomes and chloroplasts |
In the diagram showing relation between Calvin cycle and Photorespiration the molecule labeled X can be:
| 1. Oxygen 2. Ammonia 3. Nitric oxide 4. Hydrogen sulfide |
 |
Chemiosmosis in chloroplasts is possible because of:
| 1. | establishment of a proton gradient across the thylakoid membrane. |
| 2. | diffusion of electrons through the ATP synthase. |
| 3. | osmosis of water from thylakoid to stroma. |
| 4. | presence of large amount of oxygen in the stroma. |

The ATP synthase complexes in a plant cell are located:
| I: | in the thylakoid membrane |
| II: | in the plasma membrane |
| III: | in the inner mitochondrial membrane |
| 1. | I and II only | 2. | I and III only |
| 3. | II and III only | 4. | I, II and III |

In chloroplasts, protons are actively pumped from
1. the intermembrane space to the matrix.
2. the matrix to the stroma.
3. the stroma to the thylakoid space.
4. the thylakoid space to the intermembrane space.
