The first step of photosynthetic carbon fixation is catalyzed by ribulose-1,5-bisphosphate carboxylase/oxygenase, which arose when the atmosphere contained virtually no O2. The increase of atmospheric O2 caused by oxygenic photosynthesis gave rise to photorespiratory metabolism, a process whereby O2
