Question
In sugarcane plant, 14CO2 is fixed in a malic acid, in which the enzyme that fixes CO2 is
ribulose phosphate kinase
fructose phosphatase
ribulose biphosphate carboxylase
phosphoenol pyruvic acid carboxylase
Solution
D.
phosphoenol pyruvic acid carboxylase
In C4 -plants, CO2 is picked up by phosphoenol pyruvate (PEP) and the reaction being catalysed by PEP carboxylase.
