    GO ID   Ontology GO Term Definition
    15979   Photosynthesis  The Synthesis by Organisms of Organic Chemical Compounds Especially Carbohydrates From Carbon Dioxide (co2) Using Energy Obtained From Light Rather Than From the Oxidation of Chemical Compounds. 
    18298   Protein Chromophore Linkage  The Covalent or Noncovalent Attachment of a Chromophore to a Protein. 
    19684   Photosynthesis Light Reaction  The Light Reactions of Photosynthesis Which Take Place in Photosystems Ii and I. Light Energy Is Harvested and Used to Power the Transfer of Electrons Among a Series of Electron Donors and Acceptors. the Final Electron Acceptor Is Nadp+ Which Is Reduced to Nadph. Nadph Generated From Light Reactions Is Used in Sugar Synthesis in Dark Reactions. Light Reactions Also Generate a Proton Motive Force Across the Thylakoid Membrane and the Proton Gradient Is Used to Synthesize Atp. There Are Two Chemical Reactions Involved in the Light Reactions: Water Oxidation in Photosystem Ii and Nadp Reduction in Photosystem I. 
    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.
