Photorespiration is a metabolic process in plants that occurs when the enzyme RuBisCO oxygenates RuBP (ribulose-1,5-bisphosphate) instead of carboxylating it. This usually happens under conditions of high oxygen concentration and low carbon dioxide levels, often when stomata are closed to prevent water loss during hot or dry conditions. In photorespiration, RuBisCO adds oxygen to RuBP, forming one molecule of 3-phosphoglycerate (3-PGA) and one molecule of 2-phosphoglycolate. The 2-phosphoglycolate is a toxic compound that cannot enter the Calvin cycle directly, so it must be recycled through a
