[GOC:mtg_electron_transport, ISBN:0716720094]
EOG8F7R16	GO:0009055	3/48	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."

EOG8F7R16	GO:0016491	3/48	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]
