Type: Match the Following-match the column-Hard-Class 11
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Primary CO2 acceptor | (i) PEP carboxylase |
| (b) C4 acid formed in mesophyll cells | (ii) Malic acid |
| (c) Enzyme present in bundle sheath cells | (iii) RuBisCO |
| (d) 3-carbon molecule released | (iv) Pyruvate |
A
a-i, b-ii, c-iii, d-iv
B
a-i, b-ii, c-ii, d-iii
C
a-ii, b-i, c-iii, d-iv
D
a-i, b-iv, c-iii, d-ii
Correct Answer
Option A
Detailed Explanation
The primary CO2 acceptor in the C4 pathway is phosphoenol pyruvate (PEP), which is fixed by the enzyme PEP carboxylase. The C4 acid OAA is formed in the mesophyll cells, and the enzyme RuBisCO is absent in the mesophyll cells, making option A the correct match.
