    Chain A
    GO ID   Ontology GO Term Definition
    15977   Carbon Fixation  A Metabolic Process in Which Carbon (usually Derived From Carbon Dioxide) Is Incorporated Into Organic Compounds (usually Carbohydrates). 
    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. 
    19253   Reductive Pentose Phosphate Cycle  The Fixation of Carbon Dioxide (co2) As Glucose in the Chloroplasts of C3 Plants; Uses ATP and Nadph Formed in the Light Reactions of Photosynthesis; Carbon Dioxide Reacts with Ribulose 1 5 Bisphosphate (catalyzed by the Function of Ribulose Bisphosphate Carboxylase) to Yield Two Molecules of 3 Phosphoglycerate; These Are Then Phosphorylated by ATP to 1 3 Bisphosphateglyceraldehyde Which in Turn Is Then Reduced by Nadph to Glyceraldehyde 3 Phosphate. the Glyceraldehyde 3 Phosphate Is Converted to Fructose 5 Phosphate and Ribulose 5 Phosphate by Aldolase and Other Enzymes; the Ribulose 5 Phosphate Is Phosphorylated by ATP to Ribulose 1 5 Bisphosphate. 
    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. 
    9507   Chloroplast  A Chlorophyll Containing Plastid with Thylakoids Organized Into Grana and Frets or Stroma Thylakoids and Embedded in a Stroma. 
    9536   Plastid  Any Member of a Family of Organelles Found in the Cytoplasm of Plants and Some Protists Which Are Membrane Bounded and Contain Dna. Plant Plastids Develop From a Common Type the Proplastid. 
    287   Magnesium Ion Binding  Interacting Selectively and Non Covalently with Magnesium (mg) Ions. 
    4497   Monooxygenase Activity  Catalysis of the Incorporation of One Atom From Molecular Oxygen Into a Compound and the Reduction of the Other Atom of Oxygen to Water. 
    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. 
    16829   Lyase Activity  Catalysis of the Cleavage of C C C O C N and Other Bonds by Other Means Than by Hydrolysis or Oxidation or Conversely Adding a Group to a Double Bond. They Differ From Other Enzymes in That Two Substrates Are Involved in One Reaction Direction But Only One in the Other Direction. When Acting On the Single Substrate a Molecule Is Eliminated and This Generates Either a New Double Bond or a New Ring. 
    16984   Ribulose Bisphosphate Carboxylase Activity  Catalysis of the Reaction: D Ribulose 1 5 Bisphosphate + Co2 + H2o = 2 3 Phospho D Glycerate. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
