The correct statements about photosynthesis include:
| I: | the light-dependent reactions can occur only in the light, the light-independent reactions only in the dark |
| II: | photorespiration is more efficient at producing glucose than is photosynthesis |
| III: | the light-dependent reactions produce the energy-rich compounds that are used to run the light-independent reactions |
| 1. | I only | 2. | III only |
| 3. | I and III only | 4. | II and III only |
