Botany-C4 Pathway
NEET Botany C4 Pathway MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Which of the following statements about the C4 pathway is correct?
A
The primary CO2 acceptor in the C4 pathway is phosphoenol pyruvate (PEP) found in mesophyll cells.
B
RuBisCO enzyme is present in mesophyll cells of C4 plants for CO2 fixation.
C
C4 acids are formed in bundle sheath cells and directly enter the Calvin cycle.
D
Malic acid is the only 4-carbon compound produced in the C4 pathway.
Correct Answer
Option A
Detailed Explanation
The primary CO2 acceptor in the C4 pathway is indeed phosphoenol pyruvate (PEP) found in mesophyll cells, while RuBisCO is absent in these cells. C4 acids are formed in mesophyll cells and transported to bundle sheath cells, where they release CO2 for the Calvin cycle.
