Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Primary CO2 acceptor | (i) PEP case |
| (b) First C4 acid formed | (ii) Malic acid |
| (c) Location of CO2 fixation | (iii) Bundle sheath cells |
| (d) Enzyme in mesophyll cells | (iv) OAA |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-iv, c-i, d-iii
C
a-iv, b-i, c-ii, d-iii
D
a-iii, b-i, c-iv, d-ii
Correct Answer
Option A
Detailed Explanation
The primary CO2 acceptor in the C4 pathway is phosphoenol pyruvate (PEP), which is catalyzed by PEP carboxylase. The first C4 acid formed is oxaloacetic acid (OAA), located in the mesophyll cells, while the enzymes responsible for the CO2 fixation are present in these cells.
