Vedclass · Answer

(A) Photorespiration is a wasteful process that occurs in $C_3$ plants.In $C_3$ plants,the enzyme $RuBisCO$ has an affinity for both $CO_2$ and $O_2$.When $O_2$ levels are high or $CO_2$ levels are low,$RuBisCO$ acts as an oxygenase,leading to the photorespiratory pathway.$C_4$ and $CAM$ plants have evolved mechanisms to minimize photorespiration by concentrating $CO_2$ around the $RuBisCO$ enzyme,thereby suppressing its oxygenase activity.
