EOG8C5G1G GO:0006099 37/104 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."

[EC:1.3.99.1, GOC:kd] EOG8C5G1G GO:0045281 36/104 succinate dehydrogenase complex cellular_component "A multimeric complex which consists of flavoprotein (subunit A ; InterPro:IPR003952), iron-sulfur protein (subunit B) and membrane-bound cytochrome b560 (subunit C; InterPro:IPR000701). In some Archaea, the membrane-bound subunits (C or C and D) do not necessarily contain heme. Membrane-bound subunits can bind or react with quinones." [GOC:kd, InterPro:IPR000701] EOG8C5G1G GO:0009055 26/104 electron carrier 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] EOG8C5G1G GO:0016627 3/104 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] EOG8C5G1G GO:0006979 1/104 response to oxidative stress biological_process "Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of oxidative stress, a state often resulting from exposure to high levels of reactive oxygen species, e.g. superoxide anions, hydrogen peroxide (H2O2), and hydroxyl radicals." [GOC:jl, PMID:12115731] EOG8C5G1G GO:0008340 1/104 determination of adult lifespan biological_process "The control of viability and duration in the adult phase of the life-cycle." [GOC:ems] EOG8C5G1G GO:0016020 1/104 membrane cellular_component "A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it."
