| 1. | Light stimulates this reaction by forming O2 during photolysis |
| 2. | O2 is consumed and CO2 is released |
| 3. | Photorespiration is virtually non-existent in C4 plants |
| 4. | Photorespiration generates a large number of ATP molecules |
| Assertion (A): | Photorespiration is a wasteful process in plant metabolism. |
| Reason (R): | Photorespiration consumes energy and produces a toxic compound that reduces the efficiency of photosynthesis. |
