Glycolysis Priming Phase

First Step of Glycolysis

Phosphorylation of Glucose

Glucose + ATP → Glucose-6-Phosphate + ADP

What enzyme is used in the first step of glycolysis

Hexokinase/Glucokinase

Second Step of Glycolysis

Isomerization of Glucose-6-Phosphate

Glucose-6-Phosphate → Fructose-6-Phosphate

What enzyme is used in the second step of glycolysis

Glucose Phosphate Isomerase

Third Step of Glycolysis

Phosphorylation of Fructose-6-Phosphate

Fructose-6-Phosphate + ATP → Fructose-1,6-Bisphosphate + ADP

What enzyme is used in the third step of Glycolysis

Phosphofructokinase

Fourth Step of Glycolysis

Cleavage of Fructose-1,6-Bisphosphate

Fructose-1,6-Bisphosphate → Dihydroxyacetone phosphate + Glyceraldehyde-3-Phosphate

What enzymes are used in the fourth step of glycolysis

Aldolase

Fifth Step of Glycolysis

Isomerization of Dihydroxyacetone Phosphate

Dihydroxyacetone Phosphate → Glyceraldehyde-3-Phosphate

What enzyme is used in the fifth step of glycoysis

Triose Phosphate Isomerase
