Botany-C4 Pathway
NEET Botany C4 Pathway Match the Following Question
Type: Match the Following-match the column-Easy-Class 11
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
Choose the correct matching:
A
a-i, b-iv, c-iii, d-ii
B
a-ii, b-iv, c-i, d-iii
C
a-iii, b-ii, c-iv, d-i
D
a-i, b-ii, c-iv, d-iii
Correct Answer
Option A
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).
