    GO ID   Ontology GO Term Definition
    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. 
    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. 
    4096   Catalase Activity  Catalysis of the Reaction: 2 Hydrogen Peroxide = O2 + 2 H2o. 
    4097   Catechol Oxidase Activity  Catalysis of the Reaction: 2 Catechol + O2 = 2 1 2 Benzoquinone + 2 H2o.
