Gluconeogenesis begins with mitochondrial oxaloacetate being converted to phosphoenolpyruvate (pep) by either mitochondrial or cytosolic phosphoenolpyruvate carboxykinase (pepck) ( fig. 1 ). open in a separate window. figure 1. overview of carbohydrate metabolism. simple sugars, such as glucose, fructose, or galactose, have different points of.

Finally, a series of reactions generates glucose itself. in gluconeogenesis (as compared to glycolysis), the enzyme hexokinase is replaced by glucose 6 phosphatase, and the enzyme phosphofructokinase 1 is replaced by fructose 1,6 bisphosphatase. this helps the cell to regulate glycolysis and gluconeogenesis independently of each other. Gluconeogenesis refers to a group of metabolic reactions in cytosol and mitochondria to maintain the blood glucose level constant throughout the fasting state. reactions in the gluconeogenesis pathway are regulated locally and globally (by insulin, glucagon, and cortisol), and some of them are highly exergonic and irreversible.[1] the balance between stimulatory and inhibitory hormones.
