Gluconeogenesis 2.0 / 5 based on 1 rating ? BiologyUniversityOther Created by: jessicaCreated on: 18-12-12 09:25 What is the first step in Gluconeogenesis? Pyruvate is carboxylated into oxaloacetate, releasing ATP to ADP and Pi 1 of 8 What enzyme is used in the first step? Pyruvate carboxylase 2 of 8 What happens in the second step? Oxaloacetate is decarboxylated, then phosphorylated forming phosphoenolpyruvate 3 of 8 What is the enzyme in the second step? Phosphoenolpyruvate carboxykinase 4 of 8 What happens in the third step? Phosphoenolpyruvate then forms fructose 1,6 bisphosphate 5 of 8 What happens in the fourth step? Fructose 1,6 bisphosphate is converted to fructose 6 phosphate 6 of 8 What is the enzyme used in the fourth step? citrate and fructose 1,6 bisphosphatase 7 of 8 What is the fifth step? Fructose 6 phosphate is converted into glucose 8 of 8
