WebGluconeogenesis [1] is a metabolic pathway consisting of a series of eleven enzyme-catalyzed reactions, resulting in the generation of glucose from non-carbohydrates substrates. The beginning of this process takes place in the mitochondrial matrix, where pyruvate molecules are found. WebTCA intermediates are converted to malate by TCA Cycle reactions. Malate exits the mitochondria to the cytosol, where it is converted to oxaloacetate, which is subsequently converted to glucose via the reactions of gluconeogenesis.
