    Chain A,B
    GO ID   Ontology GO Term Definition
    6094   Gluconeogenesis  The Formation of Glucose From Noncarbohydrate Precursors Such As Pyruvate Amino Acids and Glycerol. 
    6096   Glycolytic Process  The Chemical Reactions and Pathways Resulting in the Breakdown of a Carbohydrate Into Pyruvate with the Concomitant Production of a Small Amount of Atp. 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. 
    6098   Pentose Phosphate Shunt  The Glucose 6 Phosphate Catabolic Process in Which Coupled to Nadph Synthesis Glucose 6 P Is Oxidized with the Formation of Carbon Dioxide (co2) and Ribulose 5 Phosphate; Ribulose 5 P Then Enters a Series of Reactions Interconverting Sugar Phosphates. the Pentose Phosphate Pathway Is a Major Source of Reducing Equivalents For Biosynthesis Reactions and Is Also Important For the Conversion of Hexoses to Pentoses. 
    8152   Metabolic Process  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. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    3824   Catalytic Activity  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. 
    4807   Triose Phosphate Isomerase Activity  Catalysis of the Reaction: D Glyceraldehyde 3 Phosphate = Glycerone Phosphate. 
    16853   Isomerase Activity  Catalysis of the Geometric or Structural Changes Within One Molecule. Isomerase Is the Systematic Name For Any Enzyme of EC Class 5.
