the change in fructose 2,6-bisphosphate concentration can be partly explained by the rise of the bifunctional enzyme , but also by an early increase in the concentration of fructose 6-phosphate , the substrate of all phosphofructokinases , and also by the decrease in the concentration of glycerate 3-phosphate , a potent inhibitor of phosphofructokinase 2 .
