NEET Botany C4 Pathway MCQ Question
Type: MCQ-numerical-Easy-Class 11
In the C4 pathway, if 100 molecules of CO2 are fixed, how many molecules of the primary CO2 acceptor phosphoenol pyruvate (PEP) are needed?
A
100
B
200
C
300
D
400
Correct Answer
Option A
Detailed Explanation
In the C4 pathway, each CO2 molecule is initially fixed by phosphoenol pyruvate (PEP) to form a 4-carbon compound. Therefore, 100 molecules of CO2 require 100 molecules of PEP since each CO2 is accepted by one PEP.
