    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. 
    42744   Hydrogen Peroxide Catabolic Process  The Chemical Reactions and Pathways Resulting in the Breakdown of Hydrogen Peroxide (h2o2). 
    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. 
    4601   Peroxidase Activity  Catalysis of the Reaction: Donor + Hydrogen Peroxide = Oxidized Donor + 2 H2o. 
    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. 
    20037   Heme Binding  Interacting Selectively and Non Covalently with Heme Any Compound of Iron Complexed in a Porphyrin (tetrapyrrole) Ring. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
