MF

succinate dehydrogenase activity

Catalysis of the reaction: succinate + acceptor = fumarate + reduced acceptor.

GO:0005739

CC

mitochondrion

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.

GO:0005749

CC

mitochondrial respiratory chain complex II, succinate dehydrogenase complex (ubiquinone)

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 o

GO:0006099

BP

tricarboxylic acid cycle

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 s

GO:0006121

BP

mitochondrial electron transport, succinate to ubiquinone

The transfer of electrons from succinate to ubiquinone that occurs during oxidative phosphorylation, mediated by the multisubunit enzyme known as complex II.

GO:0008177

MF

succinate dehydrogenase (ubiquinone) activity

Catalysis of the reaction: succinate + ubiquinone = fumarate + ubiquinol.

GO:0009055

MF

electron transfer activity

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 severa

GO:0009061

BP

anaerobic respiration

The enzymatic release of energy from inorganic and organic compounds (especially carbohydrates and fats) which uses compounds other than oxygen (e.g. nitrate, sulfate) as the terminal electron acceptor.

GO:0045273

CC

respiratory chain complex II

A part of the respiratory chain, containing 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.

GO:0050660

MF

flavin adenine dinucleotide binding

Interacting selectively and non-covalently with FAD, flavin-adenine dinucleotide, the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes, in either the oxidized form, FAD, or the reduced form, FADH2.
