II: | They occur in darkness and they are not light-dependent. |
1. | Both I and II are correct and II explains I |
2. | Both I and II are correct but II does not explain I |
3. | I is correct but II is incorrect |

How many carbon atoms does the primary carbon dioxide acceptor have in C3 photosynthesis?
1. | 2 | 2. | 3 |
3. | 4 | 4. | 5 |
How many ATP and NADPH are respectively required to make one molecule of glucose through the Calvin pathway?
1. 3 and 2 | 2. 6 and 6 |
3. 9 and 6 | 4. 18 and 12 |
The pathway:
1. is common to all plants
2. takes place in mesophyll cells in plants
3. takes place in bundle sheath cells in plants
4. does not take place in CAM plants
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 number of turns of Calvin cycle required to produce one molecule of Glyceraldehyde 3 Phosphate is:
1. | 1 | 2. | 2 |
3. | 3 | 4. | 6 |
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
