Q. Select the wrongly matched pair with regard to $C_{4}$ cycle.
A) Primary $CO_{2}$ fixation-PGA product
B) Site of initial-Mesophyll cells carboxylation
C) Primary $CO_{2}$ acceptor-PEP
D) $C_{4}$ plant-Maize
Explanation
The primary $CO_{2}$ fixation product in $C_{4}$cycle is oxaloacetic acid (OAA) in the mesophyll cells. It then from the other 4-carbon compounds like malic acid or aspartic acid in the mesophyll cells itself, which are transported to the bundle sheath cells.
