RuBisCO catalyses the carboxylation of
AGlucose-6-phosphate with ATP in cycle
BRibulose-1,5-bisphosphate with CO2
CPhosphoenolpyruvate with CO2 in mesophyll
DOxaloacetic acid with NADPH in cycle
Answer & Solution
Correct answer: B. Ribulose-1,5-bisphosphate with CO2
RuBisCO (ribulose bisphosphate carboxylase-oxygenase) catalyses RuBP + CO2 to 2 molecules of 3-PGA. It is the most abundant enzyme in the biosphere. PEPcase carboxylates PEP in C4 plants (not RuBisCO).
