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
Glucose-6-Phosphate is rearranged into what?
Via what enzyme?
- Fructose-6-Phosphate
- enzyme = Phosphoglucoisomerase
Fructose-6-Phosphate is phosphoralated into what?
Via What?
- Fructose-1,6-Biphosphate
- Enzyme = PhosphoFructokinase (PFK)
- Cost = 1 ATP
What is Fructose-1,6-biphosphate cleaved into?
Via what enzyme?
- GlycerAldehyde-3-Phosphate & Dihydroxyacetone-3-Phos
- Enzyme = Aldolase
What is Dihydroxyacetone-3-Phosphate (DHA3P) made into?
Via what enzyme?
- GlycerAldehyde-3-Phosphate
- Enzyme = Trios Phosphate Isomerase
What is the total ATP cost of Preparatory / Investment Phase?

2 ATP
What is the final product of the Preparatory Phase?

GlycerAldehyde-3-Phosphate
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
What are the 2 Glycerate-1,3-Biphosphate converted to and what is gained?
- 3-Phosphoglycerate
- Gain 1 ATP per molecule = 2 ATP
What are the two, 3-Phosphoglycerate molecules converted to?

2-Phosphoglycerate
What is 2-Phosphoglycerate converted to when it loses H2O?

Phosphoenolpyruvate (PEP)
What are the two Phosphoenolpyruvate (PEP) made into when it is phosphorolysed? What does it gain?
- Pyruvate
- Gain = 1 ATP per molecule = 2 ATP
What is the gross gain of ATP per Glucose molecule in Glycolysis?

Gross gain 4 ATP
What is the net ATP gain per glucose in glycolysis?

2 ATP
What is the ATP Equivalent per glucose molecule in Glycolysis?

2 NADH = 6 ATP + 1 ATP + 1 ATP = 8 ATP EQUI
