Phosphofructokinase is an allosteric enzyme that catalyzes the conversion of fructose 6-phosphate to fructose 1,6-bisphosphate. This a an early reaction in the glycolysis pathway that is a regulatory step in the pathway. An increase int he amount of ATP in the cell might cause decrease in the amount of phosphofructokinase enzyme by a process called feedback inhibition. Glycolysis process is regulated at various steps in which conversion of fructose 6-phosphate to fructose 1,6-bisphosphate is one of the regulatory step.

Answer: In the presence of oxygen, an increase in the amount of ATP in a cell would be expected to INHIBIT THE PHOSPHOFRUCTOKINASE ENZYME AND SLOWS THE RATE OF GLYCOLYSIS.
