NEET Botany C4 Pathway MCQ Question
Which of the following statements about the C4 pathway is correct?
The primary CO2 acceptor in C4 plants is phosphoenol pyruvate (PEP), which is found in mesophyll cells.
RuBisCO enzyme is primarily responsible for the initial CO2 fixation in C4 plants.
C4 acids are exclusively formed in the bundle sheath cells of C4 plants.
Malic acid is not involved in the C4 pathway as a 4-carbon compound.
Correct Answer
Detailed Explanation
The primary CO2 acceptor in C4 plants is indeed phosphoenol pyruvate (PEP), which is located in mesophyll cells. The other statements are incorrect as RuBisCO is not the primary enzyme in C4 plants, C4 acids are formed in mesophyll cells and transported to bundle sheath cells, and malic acid is one of the 4-carbon compounds involved in the pathway.
