Organic Chemistry of Metabolic Pathways

Metabolic pathways allude to the arrangement of chemical catalyzed reactions that lead to the transformation of a substance into the final product. Metabolic pathways incorporate a progression of reaction where the substrate is changed continuously and the transitional metabolites are persistently recovered.

Glucogenesis

Glucogenesis is a metabolic pathway in which glucose is produced from carbon substrates that are not carbohydrates. This process is observed in plants, animals, fungi, bacteria and other micro organisms. The general definition for glucogenesis or gluconeogenesis is as follows,

Anaerobic glycolysis (i.e., lactic acid fermentation) produces pyruvate that is then converted to lactate through the activity of lactate dehydrogenase. The conversion of pyruvate to lactate would seem to be an unnecessary step, since this process does not result in any further release of energy. Explain the necessity for the production of lactate as the endpoint for anaerobic glycolysis.
