Vedclass · Answer

(A) Photorespiration is a process that occurs in $C_3$ plants when the enzyme $RuBisCO$ acts as an oxygenase instead of a carboxylase.This happens primarily when the concentration of $O_2$ is high and the concentration of $CO_2$ is low in the vicinity of the enzyme.Under these conditions,$RuBisCO$ binds with $O_2$ instead of $CO_2$,leading to the formation of one molecule of phosphoglycerate and one molecule of phosphoglycolate,which initiates the photorespiratory pathway.Therefore,high $O_2$ and low $CO_2$ concentrations induce photorespiration.
