NEET Botany C4 Pathway MCQ Question
Which of the following statements about the C4 pathway is correct?
The primary CO2 acceptor in the C4 pathway is phosphoenol pyruvate.
RuBisCO enzyme is abundant in the mesophyll cells.
C4 acids are formed in bundle sheath cells.
Malic acid is the only product transported to the bundle sheath cells.
Correct Answer
Detailed Explanation
The primary CO2 acceptor in the C4 pathway is indeed phosphoenol pyruvate (PEP), which is present in the mesophyll cells. The mesophyll cells lack RuBisCO, and C4 acids are formed in the mesophyll cells, not the bundle sheath cells.
