Vedclass · Answer

(D) $RuBisCO$ (Ribulose$-1,5-$bisphosphate carboxylase-oxygenase) is a bifunctional enzyme.$1$. In the $C_3$ cycle (Calvin cycle),it acts as a carboxylase,catalyzing the fixation of $CO_2$ to $RuBP$.$2$. In $C_4$ plants,although $PEP$ carboxylase is the primary carboxylase,$RuBisCO$ still performs the carboxylation step within the bundle sheath cells.$3$. In the presence of high $O_2$ concentration,$RuBisCO$ acts as an oxygenase,initiating the $C_2$ pathway or photorespiration.Therefore,it performs all the mentioned functions.
