  1. What is glucose turned into in the first step and what is the enzyme?
    • Glucose gains one phosphate to become Glucose-6-Phosphate
    • Hexokinase is the enzyme
    • costs 1 ATP
  2. Glucose-6-Phosphate is rearranged into what? 
    Via what enzyme?
    • Fructose-6-Phosphate
    • enzyme = Phosphoglucoisomerase
  3. Fructose-6-Phosphate is phosphoralated into what? 
    Via What?
    • Fructose-1,6-Biphosphate
    • Enzyme = PhosphoFructokinase (PFK)
    • Cost = 1 ATP
  4. What is Fructose-1,6-biphosphate cleaved into?
    Via what enzyme?
    • GlycerAldehyde-3-Phosphate & Dihydroxyacetone-3-Phos
    • Enzyme = Aldolase
  5. What is Dihydroxyacetone-3-Phosphate (DHA3P) made into?
    Via what enzyme?
    • GlycerAldehyde-3-Phosphate
    • Enzyme = Trios Phosphate Isomerase
  6. What is the total ATP cost of Preparatory / Investment Phase?
    2 ATP
  7. What is the final product of the Preparatory Phase?
    GlycerAldehyde-3-Phosphate
  8. What are the 2 glyceraldehyde-3-phosphate molecules turned into in the first step of the pay off phase?
    • Glycerate-1,3-Biphosphate
    • Gain one NADH per Molecule = 2 NADH
  9. What are the 2 Glycerate-1,3-Biphosphate converted to and what is gained?
    • 3-Phosphoglycerate
    • Gain 1 ATP per molecule = 2 ATP
  10. What are the two, 3-Phosphoglycerate molecules converted to?
    2-Phosphoglycerate
  11. What is 2-Phosphoglycerate converted to when it loses H2O?
    Phosphoenolpyruvate (PEP)
  12. What are the two Phosphoenolpyruvate (PEP) made into when it is phosphorolysed? What does it gain?
    • Pyruvate
    • Gain = 1 ATP per molecule = 2 ATP
  13. What is the gross gain of ATP per Glucose molecule in Glycolysis?
    Gross gain 4 ATP
  14. What is the net ATP gain per glucose in glycolysis?
    2 ATP
  15. What is the ATP Equivalent per glucose molecule in Glycolysis?
    2 NADH = 6 ATP + 1 ATP + 1 ATP = 8 ATP EQUI
