If that doesn't help, you may need a new driver. Go to your laptop manufacturer's web site and search for your model number and the words touchpad driver. See if there's a driver you can download and install.
Mechanism and Regulation of Phosphofructokinase. Phosphofructokinase binds both Mg2+-ATP and fructose-6-phosphate (F6P) to make fructose-1,6-bisphosphate and Mg2+-ADP. Although the image with both of these products has not been determined, bound to the enzyme has been. There are three ligand binding sites per subunit.
Now, our molecule has 2 high-energy phosphates. This is the most regulated step in glycolysis. It is catalyzed by phosphofructokinase 1 or PFK 1. This step is activated by low cellular energy such as when the cell is high in AMP, ADP, Fructose-1,6-bisphosphate, and Fructose-2,6-bisphosphate.
