Question

The first product of CO2 fixation in C4 plants is (A) PGA (B) oxaloacetic acid (C) malic acid (D) PEP

Tardigrade Admin · Accepted Answer

In C 4 plants initial fixation of CO 2 occurs in mesophyll cells. It produces oxaloacetic acid as the first stable product of CO 2 fixation; while phosphoglyceraldehyde (PGA) is the first product of CO 2 fixation in C 3 plants.
