Assertion: The first product of `CO_(2)` fixation in `C_(3)` pathway is OA A.
Reason: The first product of `CO_(2)` fixation in `C_(4)` pathway is PGA.

Text Solution

Verified by Experts

The correct Answer is:
D
The first product of `CO_(2)` fixation in `C_(3)` pathway is 3-phosphoglyceric acid (PGA) which is a 3-carbon compound while the first product of `CO_(2)` fixation in `C_(4)` pathway is oxaloacetic acid (OA A) which is a 4-carbon compound.
