    5975   Carbohydrate Metabolic Process  The Chemical Reactions and Pathways Involving Carbohydrates Any of a Group of Organic Compounds Based of the General Formula Cx(h2o)y. Includes the Formation of Carbohydrate Derivatives by the Addition of a Carbohydrate Residue to Another Molecule. 
    6006   Glucose Metabolic Process  The Chemical Reactions and Pathways Involving Glucose the Aldohexose Gluco Hexose. D Glucose Is Dextrorotatory and Is Sometimes Known As Dextrose; It Is an Important Source of Energy For Living Organisms and Is Found Free As Well As Combined in Homo and Hetero Oligosaccharides and Polysaccharides. 
    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 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. 
    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. 
    12501   Programmed Cell Death  A Process Which Begins When a Cell Receives an Internal or External Signal and Activates a Series of Biochemical Events (signaling Pathway). the Process Ends with the Death of the Cell. 
    16310   Phosphorylation  The Process of Introducing a Phosphate Group Into a Molecule Usually with the Formation of a Phosphoric Ester a Phosphoric Anhydride or a Phosphoric Amide. 
    44281   Small Molecule Metabolic Process  The Chemical Reactions and Pathways Involving Small Molecules Any Low Molecular Weight Monomeric Non Encoded Molecule. 
    61621   Canonical Glycolysis  The Glycolytic Process That Begins with the Conversion of Glucose to Glucose 6 Phosphate by Glucokinase Activity. Glycolytic Processes Are the Chemical Reactions and Pathways Resulting in the Breakdown of a Carbohydrate Into Pyruvate with the Concomitant Production of a Small Amount of Atp. 
    5634   Nucleus  A Membrane Bounded Organelle of Eukaryotic Cells in Which Chromosomes Are Housed and Replicated. in Most Cells the Nucleus Contains All of the Cell's Chromosomes Except the Organellar Chromosomes and Is the Site of RNA Synthesis and Processing. in Some Species or in Specialized Cell Types RNA Metabolism or DNA Replication May Be Absent. 
    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. 
    4743   Pyruvate Kinase Activity  Catalysis of the Reaction: ATP + Pyruvate = Adp + Phosphoenolpyruvate. 
    5515   Protein Binding  Interacting Selectively and Non Covalently with Any Protein or Protein Complex (a Complex of Two or More Proteins That May Include Other Nonprotein Molecules). 
    5524   ATP Binding  Interacting Selectively and Non Covalently with ATP Adenosine 5' Triphosphate a Universally Important Coenzyme and Enzyme Regulator.
