All of the following are true about fructose-1-6-bisphosphatase, EXCEPT:-: (A) Key gluconeogenic enzyme, (B) Fructose-2,6, bisphosphate is an allosteric activator of this enzyme, (C) Catalyses the hydrolysis reaction, (D) Requires magnesium for the catalysis
Answer is B. Fructose 1,6 bisphosphatase reverses the PFK-1 reaction. So, it is a key-gluconeogenic enzyme- option 1 is true. Reaction catalysed is a hydrolysis reaction- option 3 is true Option 4-Requires magnesium for the catalysis Fructose-2,6, bisphosphate is potent allosteric activator of PFK-1 and inhibitor of fructose-1-6-bisphosphatase (option 2 is false).
