Formation of oxaloacetate by carboxylation of phosphoenol pyruvate $(PEP)$ in the mesophyll cells

Vedclass · Answer

(D) In the $C_4$ cycle (Hatch and Slack pathway),the primary $CO_2$ acceptor is phosphoenolpyruvate $(PEP)$.This reaction occurs in the mesophyll cells of the leaves.The enzyme $PEP$ carboxylase catalyzes the carboxylation of $PEP$ to form a $4-carbon$ compound known as oxaloacetic acid $(OAA)$.Therefore,the first stable product of $CO_2$ fixation in the $C_4$ cycle is oxaloacetate,formed in the mesophyll cells.
