Answer:
Phosphofructokinase is an allosteric enzyme that catalyzes the conversion of fructose 6-phosphate to fructose 1,6-bisphosphate, an early step of glycolysis. In the presence of oxygen, an increase in the amount of ATP in a cell would be expected to inhibit the enzyme and thus increase the rates of glycolysis and the citric acid cycle
Explanation:
Phosphofructokinase is also a regulatory enzyme of glycolysis. It is inhibited allosterically by elevated levels of ATP, which act as an energy-rich signal indicating an abundance of high-energy compounds.
Elevated levels of citrates also inhibits it.
While it is allosterically activated by AMP, which signals that the nergy stores are depleted.
