Which enzyme is allosterically activated by fructose-2,6-bisphosphate, thereby promoting glycolysis in the liver?

✓ Correct Answer: Option B

Fructose-2,6-bisphosphate is a potent allosteric activator of phosphofructokinase-1 (PFK-1), the committed step in glycolysis. It also inhibits fructose-1,6-bisphosphatase, suppressing gluconeogenesis.
