In C4 plants, the primary CO2 acceptor is
ARibulose bisphosphate in mesophyll
BOxaloacetate in bundle sheath cells
C3-Phosphoglycerate in bundle sheath
DPhosphoenolpyruvate (PEP) in mesophyll
Answer & Solution
Correct answer: D. Phosphoenolpyruvate (PEP) in mesophyll
PEP (3-carbon) in mesophyll cells is the primary CO2 acceptor of the C4 pathway, catalysed by PEP carboxylase. The product OAA (4-carbon) is the first stable product. RuBisCO acts only in bundle sheath cells of C4 plants.
