Q. No.The reactions of the Calvin cycle can take place as long as which of the following products of the light dependent reactions are available?
1.
Water and Glucose
2.
Water and ATP
3.
Oxygen and Carbon dioxide
4.
ATP and NADPH
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 |
