WebGlycolysis is the process of converting glucose into pyruvate and generating small amounts of ATP (energy) and NADH (reducing power). It is a central pathway that produces important precursor metabolites: six-carbon compounds of glucose-6P and fructose-6P and three-carbon compounds of glycerone-P, glyceraldehyde-3P, glycerate-3P, … WebGluconeogenesis is the synthesis of glucose. It is basically glycolysis run backwards; three new reactions (involving four new enzymes) make the standard free energy favorable. Glycolysis: Δ G o ′ = − 74 kcal/mol.
