Glycolysis

  1. glucose converted to glucose 6-phosphate by hexokinase

    1. ATP used, produces ADP

  2. glucose 6-phosphate converted to fructose 6-phosphate by phosphoglucose isomerase

  3. fructose 6-phosphate converted to fructose 1, 6-biphosphate by phosphofructokinase

    1. ATP used, produces ADP

  4. fructose 1, 6-biphosphate converted to dihydroxyacetone phosphate and glyceraldehyde 3-phosphate by aldolase and isomerase

  5. glyceraldehyde 3-phosphate converted to 2 1, 3-biphosphoglycerate by glyceraldehyde 3-phosphate dehydrogenase

    1. NAD+ used, produces NADH

    2. Pi used

  6. 3-phosphoglycerate (3PG) converted to 2-phosphoglycerate by phosphoglyceromutase

    1. isomerization

  7. 2PG converted to PEP by enolase

    1. H2O removed

  8. PEP converted to pyruvate by pyruvate kinase

    1. substrate level phosphorylation
