WebThe means by which Mg2+ and Mg2+ chelates of adenine nucleotides regulate the most important glycolytic enzymes--hexokinase, phosphofructokinase, aldolase, phosphoglycerate kinase, and pyruvate kinase--are described in detail. Creatine kinase, which is important in energy metabolism and highly sensitive to both metal ions and pH, is also discussed. WebFigure 1. Induction of glycolysis by hypoxia is dependent on growth factor signals. (A) Cells were cultured in the presence or absence (3 wk) of IL-3.Following 24 h incubation at 21% O 2 or 1.5% O 2, cellular glucose utilization was measured by the conversion of 5-3 H-glucose to 3 H 2 O.
