The products of non-cyclic photophosphorylation include:

1.	ATP and P700	2.	ATP and NADPH
3.	ADP and NADP	4.	P700 and P680

The ${\mathrm{C}}_3$ and ${\mathrm{C}}_4$ photosynthesis pathways are so called because the initial carbon fixation product in them are respectively:

The extra ATP required [as compared to NADPH] in Calvin cycle comes from:

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

Light dependent reactions are so called because they require light:

The chronological order of organelles involved in the photorespiration cycle is:

The space of thylakoid is separated from the stroma by a membrane. If the membrane capability to maintain an environment in the thylakoid space distinct from stroma is compromised, the process most directly affected would be:

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:

Given below is the schematic diagram of photorespiration pathway. The molecules labeled as A and B are respectively:

1. Serine and Glycine
2. Glycine and Serine
3. Glycine and Alanine
4. Alanine and Glycine
