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.
The concentration of Fructose-2,6-bisphosphate is lowered so glycolysis is inhibited. When PFK-2/F-2,6-bisphosphatase is phosphorylated (P*) by Protein kinase A in muscle, PFK-2 is activated and F-2,6-bisphosphatase is inhibited. The concentration of Fructose-2,6-bisphosphate is raised so glycolysis is activated.P and P* are two different sites on the PFK-2/F-2,6-bisphosphatase enzyme complex. The addition of P inhibits PFK-2 in liver but the addition of P* activates PFK-2 in muscle.I cannot explain the mechanism of activation of PFK-2 and glycolysis by insulin in muscle but it is the major control point. and P* are two different sites on the PFK-2/F-2,6-bisphosphatase enzyme complex. The addition of P inhibits PFK-2 in liver but the addition of P* activates PFK-2 in muscle.
