    GO ID   Ontology GO Term Definition
    10038   Response to Metal Ion  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 a Metal Ion Stimulus. 
    34599   Cellular Response to Oxidative Stress  Any Process That Results in a Change in State or Activity of a Cell (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. 
    45454   Cell Redox Homeostasis  Any Process That Maintains the Redox Environment of a Cell or Compartment Within a Cell. 
    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. 
    4601   Peroxidase Activity  Catalysis of the Reaction: Donor + Hydrogen Peroxide = Oxidized Donor + 2 H2o. 
    8379   Thioredoxin Peroxidase Activity  Catalysis of the Reaction: Thioredoxin + Hydrogen Peroxide = Thioredoxin Disulfide + H2o. 
    16209   Antioxidant Activity  Inhibition of the Reactions Brought About by Dioxygen (o2) or Peroxides. Usually the Antioxidant Is Effective Because It Can Itself Be More Easily Oxidized Than the Substance Protected. the Term Is Often Applied to Components That Can Trap Free Radicals Thereby Breaking the Chain Reaction That Normally Leads to Extensive Biological Damage. 
    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. 
    51920   Peroxiredoxin Activity  Catalysis of the Reaction: 2 R' Sh + Rooh = R' S S R' + H2o + Roh.
