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) PEP carboxylase (c) First C4 acid formed (iii) Oxaloacetic acid (d) Location of initial fixation (iv) Bundle sheath cells
Choose the correct matching:
A
a-iii, b-ii, c-i, d-iv
B
a-ii, b-iii, c-iv, d-i
C
a-i, b-iv, c-iii, d-ii
D
a-iii, b-i, c-ii, d-iv
Correct Answer
Option A
Detailed Explanation
The primary CO2 acceptor in the C4 pathway is oxaloacetic acid (OAA), formed from phosphoenol pyruvate (PEP) through the action of PEP carboxylase. The correct pairings highlight the roles of these components in the C4 pathway as described in the NCERT context.
