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.
When ATP levels are high in the cell, the cell no longer needs metabolic energy production to occur. In this case, PFK's activity is inhibited by allosteric regulation by ATP itself, closing the valve on the flow of carbohydrates through glycolysis.Source(s): http://www.wiley.com/legacy/college/boye...he majority of the ATP in the cell is produced by the Electron Transport System located in the mitochondrion. Under aerobic conditions, the pyruvate produced in the glycolystic pathway enters the mitochondrion and is converted to acetyl CoA by the enzyme pyruvate dehydrogenase.
