This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Gluconeogenesis, Subject name: Biochemistry
[{'content': 'All of the following are true about fructose-1-6-bisphosphatase, EXCEPT:- \nSelect and explain. \nA. 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', 'role': 'user'}, {'content': 'Answer: B \nExplanation: 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).', 'role': 'assistant'}]
