Glycolysis enzymes basic function

Hexokinase step 1

glucose to glucose 6-phosphate

Phosphohexose isomerase step 2

glucose 6-phosphate to fructose 6-phosphate

Phosphofructokinase (PFK1) step 3

fructose 6-phosphate to fructose 1,6-bisphosphate

Aldose step 4

fructose 1,6-bisphosphate to glyceraldehyde 3-phosphate and dihydroxyacetone phosphate

Triose phosphate isomerase step 5

dihydroxyacetone phosphate to glyceraldehyde 3-phosphate

Glyceraldehyde 3-phosphate dehydrogenase step 6

glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate

Phosphoglycerate kinase step 7

1,3-bisphosphoglycerate to ATP + 3-phosphoglycerate

Phosphoglycerate mutase step 8

3-phosphoglycerate to 2-phosphoglycerate

Enolase step 9

2-phosphoglycerate to phosphoenolpyruvate

Pyruvate kinase step 10

phosphoenolpyruvate to pyruvate
