Photorespiration (Photosynthetic carbon oxidative or PCO cycle) is the light dependent process of oxygenation of ribulose-1,5-biphosphate (RuBP) and release of CO2 by the photosynthetic organs of a plant. Under normal conditions, in Calvin cycle, carboxylation of RuBP takes place whereas during photorespiration instead of carboxylation, oxygenation of RuBP takes place. This is due to abnormal behaviour of enzyme RuBisCO, which at high temperature (more than 35C), functions as oxygenase (instead of carboxylase). Instead of fixing CO2, it performs oxygenation of RuBP to produce a 3-carbon phosphoglyceric acid (PGA) and a 2-carbon phosphoglycolate. It is the first reaction of photorespiration and can be represented as:
In this way, photorespiration interferes with the successful functioning of Calvin cycle by causing oxygenation of RuBP instead of carboxylation.
