Photorespiration is a wasteful process. Why is it so?
1. | The number of ATP molecules produced in the pathway is very low. |
2. | The number of NADPH molecules produced in the pathway is very low. |
3. | The synthesis of sugars in the pathway requires a large input of ATP energy. |
4. | There is neither synthesis of sugars, nor of ATP in the pathway. |
