determination of intracellular concentrations of glycolytic intermediates suggests that the enhanced glycolytic flux is due to increased activities of hexokinase ( atp : d-hexose 6-phosphotransferase , ec 2.7.1.1 ) , phosphofructokinase , ( atp : d-fructose-1-phosphate 6-phosphotransferase , ec 2.7.1.56 ) , and pyruvate kinase ( atp : pyruvate 2-o-phosphotransferase , ec 2.7.1.40 ) , and not directly to the increased glucose transport .
