Gluconeogenesis & Fermentation

Gluconeogenesis

• gluconeogenesis = “sugar + new + creation”

• The “reverse” process of glycolysis

• There are three detours that occur at steps 1,3, and 10 because there is a large negative delta g so the reverse cannot occur

• Anabolic reaction (more energetically expensive than catabolic reactions)

• Glycolysis = catabolic reaction

• Glycolysis occurs in all cells

• Gluconeogenesis does not occur in all cells, occurs mostly in the liver cells (most glucose is stored in the liver)
