Vedclass · Answer

(C) Sugarcane is a $C_4$ plant. In $C_4$ plants,the primary fixation of $CO_2$ occurs in the mesophyll cells.The enzyme Phosphoenolpyruvate carboxylase (PEPCase) catalyzes the fixation of $CO_2$ by combining it with Phosphoenolpyruvate $(PEP)$ to form Oxaloacetic acid $(OAA)$.This $OAA$ is then converted into malic acid or aspartic acid,which is transported to the bundle sheath cells.Therefore,the correct enzyme involved in the initial fixation of $CO_2$ is Phosphoenolpyruvate carboxylase.

In sugarcane plant,$^{14}CO_2$ is fixed in malic acid. The enzyme that fixes $CO_2$ in this process is:
