MetaCyc Gene-Ontology-Terms Class: GO:0009055 - electron carrier activity

Synonyms: GO:0009053, GO:0009054, electron transporter activity

Definition: 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.
