In chloroplasts the ${\mathrm{CF}}_1$ part of the ATP synthase is located:
1. on the side facing the thylakoid space.
2. on the ATP molecules themselves.
3. on the pigment molecules of PS I and PS II.
4. on the stroma side of the membrane.

Identify the correct statement:

The primary function of the Calvin cycle is to:
1. use ATP to release carbon dioxide
2. use NADPH to release carbon dioxide
3. split water and release oxygen
4. fix inorganic carbon to simple sugars

What is true for both light reactions and the Calvin cycle of photosynthesis in plants?
1. Production of molecular oxygen
2. Depend directly or indirectly on light
3. Requirement of ATP
4. Production of NADPH

Neither light dependent reaction nor Calvin cycle in photosynthesis in plants require:

Which of the following must occur in the biochemical pathway of Calvin cycle?
1. addition of a pair of electrons from NADPH
2. inactivation of RuBP carboxylase enzyme
3. regeneration of ATP from ADP
4. regeneration of RuBP

Given below is the schematic diagram of Calvin cycle taking place in a certain plant. ATP used by this plant is radioactively labeled. One turn of the cycle is allowed to happen. Radioactivity would be seen in all except:

1. A
2. B
3. C and D
4. E

Oxidation of pyruvate occurs in mitochondria in pjotosthesizing cells as well. In such this occurs:
1. in photosynthetic cells in the light, while photosynthesis occurs concurrently
2. in non-photosynthesizing cells only
3.in photosynthesizing cells in dark periods and in other tissues all the time
4. in photosynthesizing cells in the light and in other tissues in the dark

For the synthesis of glucose, the source of hydrogen atoms is:

In cyclic photophosphorylation, the primary electron acceptor is:
1. An iron-sulfur protein
2. Plastocyanin
3. Plastoquinone
4. Water
