2. PS-I
3. PS-II
4. None of the above

Which pair is wrong?

1. C3-maize
2. C4-Kranz anatomy

Which is the first CO2 acceptor enzyme in C4 plants?

1. RuDP carboxylase
2. Phosphoric acid
3. RuBisCO

For assimilation of one CO2 molecule, the energy required in form of ATP and NADPH2 are

1. 2 ATP and 2 NADPH2
2. 5 ATP and 3 NADPH2
3. 3 ATP and 2 NADPH2
4. 18 ATP and 12 NADPH2

For the synthesis of one glucose molecule the Calvin cycle operates for

1. 2 times
2. 4 times
3. 6 times
4. 8 times

The first step for initiation of photosynthesis will be

1. photolysis of water
2. excitation of chlorophyll molecules due to absorption of light
3. ATP formation
4. glucose formation
