    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. 
    16020   Membrane  A Lipid Bilayer Along with All the Proteins and Protein Complexes Embedded in It an Attached to It. 
    16021   Integral Component of Membrane  The Component of a Membrane Consisting of the Gene Products and Protein Complexes Having At Least Some Part of Their Peptide Sequence Embedded in the Hydrophobic Region of the Membrane. 
    30077   Plasma Membrane Light Harvesting Complex  A Plasma Membrane Protein Pigment Complex That May Be Closely or Peripherally Associated to Photosynthetic Reaction Centers That Participate in Harvesting and Transferring Radiant Energy to the Reaction Center. Examples of This Complex Are Found in Bacterial Species. 
    42717   Plasma Membrane Derived Chromatophore Membrane  The Lipid Bilayer Associated with a Plasma Membrane Derived Chromatophore; Surrounds Chromatophores That Form Complete Vesicles. 
    16168   Chlorophyll Binding  Interacting Selectively and Non Covalently with Chlorophyll; Any Compound of Magnesium Complexed in a Porphyrin (tetrapyrrole) Ring and Which Functions As a Photosynthetic Pigment. 
    42314   Bacteriochlorophyll Binding  Interacting Selectively and Non Covalently with Bacteriochlorophyll a Form of Chlorophyll Found in Photosynthetic Bacteria Such As the Purple and Green Bacteria. There Are Several Types Designated a to G. Bacteriochlorophyll a and Bacteriochlorophyll B Are Structurally Similar to the Chlorophyll a and Chlorophyll B Found in Plants.
