NEET Botany C4 Pathway Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Primary CO2 acceptor | (i) Malic acid |
| (b) Enzyme for CO2 fixation | (ii) Bundle sheath cells |
| (c) C4 acid formation location | (iii) Mesophyll cells |
| (d) C4 acid breakdown location | (iv) PEP carboxylase |
a-i, b-iv, c-iii, d-ii
a-ii, b-iv, c-i, d-iii
a-iii, b-ii, c-iv, d-i
a-i, b-ii, c-iv, d-iii
Correct Answer
Detailed Explanation
The primary CO2 acceptor in the C4 pathway is phosphoenol pyruvate (PEP), which is present in mesophyll cells (a-iii). The enzyme responsible for CO2 fixation is PEP carboxylase (b-iv). C4 acid formation occurs in mesophyll cells (c-iii), and the breakdown of C4 acids takes place in bundle sheath cells (d-ii).
