The Chemical Reactions and Pathways Resulting in the Breakdown of a Carbohydrate Into Pyruvate with the Concomitant Production of a Small Amount of ATP and the Reduction of Nad(p) to Nad(p)h. Glycolysis Begins with the Metabolism of a Carbohydrate to Generate Products That Can Enter the Pathway and Ends with the Production of Pyruvate. Pyruvate May Be Converted to Acetyl Coenzyme a Ethanol Lactate or Other Small Molecules.
The Chemical Reactions and Pathways Including Anabolism and Catabolism by Which Living Organisms Transform Chemical Substances. Metabolic Processes Typically Transform Small Molecules But Also Include Macromolecular Processes Such As DNA Repair and Replication and Protein Synthesis and Degradation.
Catalysis of a Biochemical Reaction At Physiological Temperatures. in Biologically Catalyzed Reactions the Reactants Are Known As Substrates and the Catalysts Are Naturally Occurring Macromolecular Substances Known As Enzymes. Enzymes Possess Specific Binding Sites For Substrates and Are Usually Composed Wholly or Largely of Protein But RNA That Has Catalytic Activity (ribozyme) Is Often Also Regarded As Enzymatic.
