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.

What happens to the states of matter when the temperature changes
stepladder [879]

    They may either release heat or gain heat. With a temperature increase, the kinetic energy increases and the state of matter will increase (example, ice to water aka solid to liquid)

    If the temperature decreases, then the kinetic energy decreases and the state of matter will decrease (example, water vapor to water aka gas to liquid)

Have a nice day!

    I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
