Enzymes of Gluconeogenesis

Eleven reactions are catalyzed in glucoenogenesis. The enzymes involved and the reactions they catalyze are listed below. Glycolysis uses many of the same enzymes as gluconeogenesis, but with reversal of reaction direction. Enzymes differing between glycolysis and gluconeogenesis are marked with an asterisk (*).

* Glucose-6-Phosphatase (glycolysis uses Hexokinase)
Phosphoglucoisomerase
* Fructose-1,6-Bisphosphatase(glycolysis uses Phosphofructokinase )
Fructose-1,6-Bisphosphate Aldolase
Triosephosphate Isomerase
Glyceradehyde-3-Phosphate Dehydrogenase
Phosphoglycerate Kinase
Phosphoglycerate Mutase
Enolase
* PEPCK (Glycolysis uses Pyruvate Kinase )
Pyruvate Carboxylase (Glycolysis uses Pyruvate Kinase )
