Photorespiration is a metabolic pathway that occurs in plants in the presence of light, in which ribulose bisphosphate carboxylase/oxygenase the (RuBisCO) enzyme involved in carbon dioxide fixation with ribulose bisphosphate, accepts oxygen, in place of carbon dioxide, resulting in the formation of a twocarbon compound, glycolate. Most of the fixed carbon represented by the glycolate can be salvaged by a series of reactions-the glycolate pathway involving the peroxisomes and mitochondria, and returned to the chloroplasts. However, some of the carbon is lost as carbon dioxide. Unlike respiration there is no production of ATP.
