Glycolysis Purposes

Hexokinase Catalyzed Reaction

add 1st phosphate and trap glucose in the cell

Phosphoglucose Isomerase Catalyzed Reaction

convert aldose to ketose so that step 4 can produce two 3-carbon products

Phosphofructokinase Catalyzed Reaction

add second phosphate so that isomers created in aldolase reaction will both have one

Aldolase Catalyzed Reaction

cleaves ketose to create 3 carbon isomers which will make the reaction that produces GAP rapid for constant supply to stage 2

Triose Phosphate Catalyzed Reaction

rapidly convert DHAP to GAP for a constant supply to stage 2

Glyceraldehyde 3-Phosphate Dehydrogenase Catalyzed Reaction

create high phosphoryl transfer potential compound

Phosphoglycerate Kinase Catalyzed Reaction

Produce ATP through substrate level phosphorylation

Phosphoglycerate Mutase Catalyzed Reaction

work toward creating high phosphoryl transfer potential compound by moving phosphate

Enolase Catalyzed Reaction

create high phosphoryl transfer potential compound

Pyruvate Kinase Catalyzed Reaction

Produce ATP through substrate level phosphorylation
