    GO ID   Ontology GO Term Definition
    55114   Oxidation Reduction Process  A Metabolic Process That Results in the Removal or Addition of One or More Electrons to or From a Substance with or Without the Concomitant Removal or Addition of a Proton or Protons. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    5829   Cytosol  The Part of the Cytoplasm That Does Not Contain Organelles But Which Does Contain Other Particulate Matter Such As Protein Complexes. 
    16491   Oxidoreductase Activity  Catalysis of an Oxidation Reduction (redox) Reaction a Reversible Chemical Reaction in Which the Oxidation State of an Atom or Atoms Within a Molecule Is Altered. One Substrate Acts As a Hydrogen or Electron Donor and Becomes Oxidized While the Other Acts As Hydrogen or Electron Acceptor and Becomes Reduced. 
    16740   Transferase Activity  Catalysis of the Transfer of a Group E.g. a Methyl Group Glycosyl Group Acyl Group Phosphorus Containing or Other Groups From One Compound (generally Regarded As the Donor) to Another Compound (generally Regarded As the Acceptor). Transferase Is the Systematic Name For Any Enzyme of EC Class 2.
