  4. Main stages in glycolysis (total of 9 stages, this is a synopsis of those stages). Specific enzymes are necessary for each reaction along the way.See Fig. 8.5 in text for help

  5. Pathway of glycolysis from glucose to pyruvate. Substrates and products are in blue, enzymes are in green. The two high energy intermediates whose oxidations are coupled to ATP synthesis are shown in red (1,3-bisphosphoglycerate and phosphoenolpyruvate).

  6. Controlling Glycolysis • When cell is using ATP rapidly—glycolysis speeds up. The opposite is also true. • A major regulatory factor is the allosteric enzyme phosphofructokinase that is responsible for making fructose 1,6-biphosphate. • phosphofructokinase is inhibited by high concentrations of ATP and activated by high concentrations of ADP (both can fit the allosteric site)

  7. phosphofructokinase
