| GO term | GO name | GO namespace | GO def |
| GO:0016491 | oxidoreductase activity | molecular_function | 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. [GOC:go_curators] |
| GO:0005758 | mitochondrial intermembrane space | cellular_component | The region between the inner and outer lipid bilayers of the mitochondrial envelope. [GOC:mah] |
| GO:0022857 | transmembrane transporter activity | molecular_function | Enables the transfer of a substance, usually a specific substance or a group of related substances, from one side of a membrane to the other. [GOC:jid, GOC:mtg_transport, ISBN:0815340729] |
| GO:0005743 | mitochondrial inner membrane | cellular_component | The inner, i.e. lumen-facing, lipid bilayer of the mitochondrial envelope. It is highly folded to form cristae. [GOC:ai] |
| GO:0005739 | mitochondrion | cellular_component | A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration. [GOC:giardia, ISBN:0198506732] |
| GO:0003824 | catalytic activity | molecular_function | Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.

| GO:0022804 | active transmembrane transporter activity | molecular_function | Enables the transfer of a specific substance or related group of substances from one side of a membrane to the other, up the solute's concentration gradient. The transporter binds the solute and undergoes a series of conformational changes. Transport works equally well in either direction. [GOC:mtg_transport, ISBN:0815340729] |
| GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
| GO:0032981 | mitochondrial respiratory chain complex I assembly | biological_process | The aggregation, arrangement and bonding together of a set of components to form mitochondrial respiratory chain complex I. [GOC:rph] |
| GO:0009055 | electron transfer activity | molecular_function | Any molecular entity that serves as an electron acceptor and electron donor in an electron transport chain. An electron transport chain is a process in which a series of electron carriers operate together to transfer electrons from donors to any of several different terminal electron acceptors to generate a transmembrane electrochemical gradient. [ISBN:0198506732] |
| GO:0006120 | mitochondrial electron transport, NADH to ubiquinone | biological_process | The transfer of electrons from NADH to ubiquinone that occurs during oxidative phosphorylation. [ISBN:0716731363] |
| GO:0005747 | mitochondrial respiratory chain complex I | cellular_component | A protein complex located in the mitochondrial inner membrane that forms part of the mitochondrial respiratory chain. It contains about 25 different polypeptide subunits, including NADH dehydrogenase (ubiquinone), flavin mononucleotide and several different iron-sulfur clusters containing non-heme iron. The iron undergoes oxidation-reduction between Fe(II) and Fe(III), and catalyzes proton translocation linked to the oxidation of NADH by ubiquinone. [GOC:mtg_sensu, ISBN:0198547684] |
| GO:0005215 | transporter activity | molecular_function | Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells. [GOC:ai, GOC:dgf] |
