| GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
| GO:0009055 | electron transfer activity | molecular_function | A molecular function representing the directed movement of electrons from one molecular entity to another, typically mediated by electron carriers or acceptors, resulting in the transfer of energy and/or the reduction-oxidation (redox) transformation of chemical species. This activity is fundamental to various biological processes, including cellular respiration and photosynthesis, as well as numerous enzymatic reactions involved in metabolic pathways.

| GO:0016627 | oxidoreductase activity, acting on the CH-CH group of donors | molecular_function | Catalysis of an oxidation-reduction (redox) reaction in which a CH-CH group acts as a hydrogen or electron donor and reduces a hydrogen or electron acceptor. [GOC:ai] |
| GO:0020037 | heme binding | molecular_function | Binding to a heme, a compound composed of iron complexed in a porphyrin (tetrapyrrole) ring. [GOC:ai] |
| GO:0046872 | metal ion binding | molecular_function | Binding to a metal ion. [GOC:ai] |
| GO:0006099 | tricarboxylic acid cycle | biological_process | A nearly universal metabolic pathway in which the acetyl group of acetyl coenzyme A is effectively oxidized to two CO2 and four pairs of electrons are transferred to coenzymes. The acetyl group combines with oxaloacetate to form citrate, which undergoes successive transformations to isocitrate, 2-oxoglutarate, succinyl-CoA, succinate, fumarate, malate, and oxaloacetate again, thus completing the cycle. In eukaryotes the tricarboxylic acid is confined to the mitochondria. See also glyoxylate cycle. [ISBN:0198506732] |
| GO:0006121 | mitochondrial electron transport, succinate to ubiquinone | biological_process | The transfer of electrons from succinate to ubiquinone that occurs during oxidative phosphorylation, mediated by the multisubunit enzyme known as complex II. [ISBN:0716731363] |
| GO:0009060 | aerobic respiration | biological_process | The enzymatic release of energy from inorganic and organic compounds (especially carbohydrates and fats) which requires oxygen as the terminal electron acceptor. [GOC:das, GOC:jl, ISBN:0140513590] |
| GO:0042776 | proton motive force-driven mitochondrial ATP synthesis | biological_process | The transport of protons across a mitochondrial membrane to generate an electrochemical gradient (proton-motive force) that powers ATP synthesis. [GOC:mtg_sensu, ISBN:0716731363] |
| 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: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:0005749 | mitochondrial respiratory chain complex II, succinate dehydrogenase complex (ubiquinone) | cellular_component | A protein complex located in the mitochondrial inner membrane that forms part of the mitochondrial respiratory chain. Contains the four polypeptide subunits of succinate dehydrogenase, flavin-adenine dinucleotide and iron-sulfur. Catalyzes the oxidation of succinate by ubiquinone. Connects the TCA cycle with the respiratory chain. [GOC:mtg_sensu, GOC:vw, ISBN:0198547684] |
| GO:0016020 | membrane | cellular_component | A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. [GOC:dos, GOC:mah, ISBN:0815316194] |
