Vedclass · Answer

(B) Photorespiration is a wasteful process that occurs in plants when the enzyme $RuBisCO$ acts as an oxygenase instead of a carboxylase.In $C_3$ plants,the concentration of $CO_2$ inside the leaf is relatively low,and $RuBisCO$ is exposed to high levels of $O_2$,which leads to the oxygenation of $RuBP$ and the initiation of the photorespiratory pathway.$C_4$ plants and $CAM$ plants have evolved mechanisms to minimize photorespiration by concentrating $CO_2$ around the $RuBisCO$ enzyme,thereby suppressing its oxygenase activity.Therefore,photorespiration is a characteristic feature primarily observed in $C_3$ plants.
