Which one of the following concerns photophosphorylation:
1.
2.
3.
4.
In the sugarcane plant, 14CO2 is fixed in malic acid because the enzyme that fixes CO2 is:
1. Ribulose biphosphate carboxylase
2. Phosphoenol pyruvic acid carboxylase
3. Ribulose phosphate kinase
4. Fructose phosphatase
Which pair is wrong:
1. – Maize
2. – Kranz anatomy
3. Calvin cycle - PGA
4. Hatch and Slack cycle – O.A.A
In photosynthesis, energy from light reaction to dark reaction is transferred in the form of:
1. ADP
2. ATP
3. RUDP
4. Chlorophyll
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. | Excitement of chlorophyll molecule due to absorption of light |
3. | ATP formation |
4. | Glucose formation |
Photosynthetically active radiation (PAR) represents the following range of wavelengths:
1. 450-950 nm
2. 340-450 nm
3. 400-700 nm
4. 500-600 nm
Chemiosmotic theory of ATP synthesis in the chloroplasts and mitochondria is based on:
1. Membrane potential
2. Accumulation of K ions
3. Proton gradient
4. Accumulation of Na ions
During light reaction in photosynthesis, the following are formed
Dark reaction in photosynthesis is called so because
1. It can occur in dark also
2. It does not depend directly on light energy
3. It cannot occur during day light
4. It occurs more rapidly at night
