(C) In $C_3$ plants,the primary carboxylation reaction,which involves the fixation of atmospheric $CO_2$ into a stable organic intermediate,is catalyzed by the enzyme Ribulose$-1,5-$bisphosphate carboxylase-oxygenase,commonly known as $RuBP$ carboxylase or $RuBisCO$. This enzyme facilitates the addition of $CO_2$ to $RuBP$ to form $3$-phosphoglycerate ($3$-$PGA$).
