The first product of `CO_2` fixation in `C_4` -plants is

A

Formation of oxaloacetate by carboxylation of phosphoenolpyruvate (PEP) in bundle sheath cells

B

Formation of phosphoglyceric acid in mesophyll cells

C

Formation of bundle sheath cells

D

Formation of oxaloacetate by carboxylation of phosphoenolpyruvate (PEP) in the mesophyll cells

Text Solution

Verified by Experts

The correct Answer is:
A
In `C_4` pathway initially, the carbon dioxide of the atmosphere comes in contact with mesophyll cells where it combines with phosphoenol pyruvic acid to form oxaloacetic acid in the presence of enzyme phosphoenolpyruvate carboxylase.
