PFK-2 and fructose 2,6-bisphosphatase are two names for the same enzyme. The name PFK-2 is used for the enzyme's catalysis of the phosphorylation of fructose 6-phosphate to fructose 2,6-bisphosphate. The name fructose 2,6-bisphosphatase is used for its catalysis of the reverse reaction. What is unique about this enzyme that makes it logical to use two names?
A) It is one of very few enzymes that can catalyze both the forward and reverse reactions.
B) The enzyme is a monomer when catalyzing the phosphorylation reaction and a dimer when catalyzing the reverse reaction.
C) The forward and reverse reactions occur in different compartments within the cell, so a different name is used for each activity.
D) The enzyme is bifunctional. The forward and reverse reactions are catalyzed by different sites on the same enzyme.
