Kreb’s pointed out that energy barriers obstruct a simple Reversal of Glycolysis: Between Pyruvate and PEP (Enzymes: Pyruvate Carboxylase and Phosphoenolpyruvate Carboxylase-PEPCK) The steps of glycogenesis are as follows: Glucose phosphorylation – In the initial phase, glucose is phosphorylated into glucose-6-phosphate, a usual reaction in glycolysis. Many of them are also animated. Glycolysis slows because fructose-2,6-bisphosphate is not available to activate Phosphofructokinase. Regulating these points in the pathway can prevent "futile cycling". The pathway uses several enzymes of the glycolysis with the exception of enzymes of the irreversible steps namely pyruvate kinase, 6-phosphofructokinase, and hexokinase. The major substrates are the glucogenic amino acids (), lactate, glycerol, and propionate.Liver and kidney are the major gluconeogenic tissues; the kidney may contribute up to 40% of total glucose synthesis in the fasting state and more in starvation.
