The factors that can be limiting for the light independent reactions of photosynthesis are:
1. , temperature, and light
2. , light, and water
3. water, temperature, and
4. oxygen, water, and temperature
The wavelengths of light most useful in photosynthesis are:
1. | green and orange | 2. | red and blue |
3. | infrared and yellow | 4. | red and green |
Oxygen, during oxygenic photosynthesis, is produced during:
1. cyclic photophosphorylation
2. the light-dependent reactions involving photosystems I and II
3. Calvin cycle
4. the Krebs cycle
The greatest problem with photorespiration is faced by:
1. | C4 plants | 2. | C3 plants |
3. | CAM plants | 4. | purple sulfur bacteria |
Identify the incorrectly matched pair:
1. | PS I | P700 is reaction center |
2. | RuBP | 5 carbon compound |
3. | PS II | P680 is reaction center |
4. | C3 plants | Kranz anatomy |
The number of turns of Calvin cycle required to produce one molecule of Glyceraldehyde 3 Phosphate is:
1. | 1 | 2. | 2 |
3. | 3 | 4. | 6 |
Identify the correct statement regarding the functioning of photosystem II?
1. | The reaction center is P700. |
2. | It works after PS I in non cyclic photophosphorylation. |
3. | Water splits and carbon dioxide is released. |
4. | The electron vacancies in P680 are filled by electrons derived from water. |
The products of non-cyclic photophosphorylation include:
1. | ATP and P700 | 2. | ATP and NADPH |
3. | ADP and NADP | 4. | P700 and P680 |
The extra ATP required [as compared to NADPH] in Calvin cycle comes from:
1. | photosystem II | 2. | photosystem I |
3. | cyclic electron flow | 4. | non cyclic electron flow |
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. |
