1. In photorespiration, RuBP carboxylase acts as RuBP oxygenase in higher concentrations of oxygen.
2. Food produced in the process of photosynthesis is oxidized in light respiration. So it is a harmful method.
3. ATP is not produced in photosynthesis. So it cannot be called real breathing.
4. Photorespiration consumes ATP and NADPH+H+.
5. This process protects the plant from stress.
6. This process is indirectly beneficial for photosynthesis.
7. Glycine and serine are produced in this process.
