    GO ID   Ontology GO Term Definition
    6810   Transport  The Directed Movement of Substances (such As Macromolecules Small Molecules Ions) Into Out of or Within a Cell or Between Cells or Within a Multicellular Organism by Means of Some Agent Such As a Transporter or Pore. 
    6979   Response to Oxidative Stress  Any Process That Results in a Change in State or Activity of a Cell or an Organism (in Terms of Movement Secretion Enzyme Production Gene Expression Etc.) As a Result of Oxidative Stress a State Often Resulting From Exposure to High Levels of Reactive Oxygen Species E.g. Superoxide Anions Hydrogen Peroxide (h2o2) and Hydroxyl Radicals. 
    15671   Oxygen Transport  The Directed Movement of Oxygen (o2) Into Out of or Within a Cell or Between Cells by Means of Some Agent Such As a Transporter or Pore. 
    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.

    43025   Neuronal Cell Body  The Portion of a Neuron That Includes the Nucleus But Excludes Cell Projections Such As Axons and Dendrites. 
    4601   Peroxidase Activity  Catalysis of the Reaction: Donor + Hydrogen Peroxide = Oxidized Donor + 2 H2o. 
    5344   Oxygen Transporter Activity  Enables the Directed Movement of Oxygen Into Out of or Within a Cell or Between Cells.
