Glycolysis is the metabolic pathway that converts glucose C6H12O6, into pyruvate, CH3COCOO− + H+. The free energy released in this process is used to form the ATP and NADH. Gluconeogenesis is a metabolic pathway that results in the generation of glucose from non-carbohydrate carbon substrates such as pyruvate, lactate, glycerol, glucogenic amino acids, and fatty acids. Description adapted from [Wikipedia](http://www.wikipedia.org). This pathway was inferred from Homo sapiens pathway [http://www.wikipathways.org/index.php?title=Pathway:WP534&oldid=28564 WP534(r28564)] with a 76% conversion rate. Gck is mainly active in liver Not present in brain and muscle, so those organs can not produce their own glucose in the gluconeogenesis pathway d18
