10 steps of glycolysis

step 1 glycolysis

glucose (6C) → glucose 6 phosphate (6C) / requires ATP

step 1 enzyme

hexokinase

step 2 glycolysis

glucose 6 phosphate (6C) → fructose 6 phosphate (6C)

step 2 enzyme

phosphoglucose isomerase

step 3 glycolysis

fructose 6 phosphate (6C) → fructose 1,6 bisphosphate (6C) / requires ATP

step 3 enzyme

phosphofructokinase

what steps are the energy investment phase

steps 1-3

step 4 glycolysis

fructose 1,6 bisphosphate (6C) splits into dihydroxyl acetone phosphate (3C) and glyceraldehyde 3 phosphate (3C)

step 4 enzyme

aldolase

step 5 glycolysis

dihydroxyl acetone phosphate (3C) → glyceraldehyde 3 phosphate (3C)

step 5 enzyme

triose phosphate isomerase

what steps are the priming/ cleavage phase

steps 4-5

step 6 glycolysis

glyceraldehyde 3 phosphate (3C) → 1,3 bisphosphoglycerate / requires iP from cytosol which goes to 1st Carbon / NADH formed (NAD+ + 2e- + 2H+ → NADH = H+

step 6 enzyme

glyceraldehyde 3 phosphate dehydrogenase

step 7 glycolysis

1, 3 bisphosphoglycerate (3C) → 3 phosphoglycerate (3C) / requires ATP

step 7 enzyme

phosphoglycerokinase

step 8 glycolysis

3 phosphoglycerate (3C) → 2 phosphoglycerate (3C)

step 8 enzyme

phosphoglyceromutase

step 9 glycolysis

2 phosphoglycerate (3C)→ phosphoenolpyruvate (3C) / h2O is lost

step 9 enzyme

enolase

step 10 glycolysis

phosphoenolpyruvate (3C) → pyruvate (3C) / ATP is produced

step 10 enzyme

pyruvate kinase

what steps are the energy liberation phase

steps 6-10
