GO
GO:0016655 Catalysis of an oxidation-reduction (redox) reaction in which NADH or NADPH acts as a hydrogen or electron donor and reduces a quinone or a similar acceptor molecule. GO:0009276 The peptidoglycan layer of the Gram-negative cell envelope. In Gram-negative cells the peptidoglycan is relatively thin (1-2nm) and is linked to the outer membrane by lipoproteins. In Gram-negative cells the peptidoglycan is too thin to retain the primary stain in the Gram staining procedure and therefore cells appear red after Gram stain. GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. GO:0022904 A process in which a series of electron carriers operate together to transfer electrons from donors such as NADH and FADH2 to any of several different terminal electron acceptors to generate a transmembrane electrochemical gradient. GO:0012505 A collection of membranous structures involved in transport within the cell. The main components of the endomembrane system are endoplasmic reticulum, Golgi bodies, vesicles, cell membrane and nuclear envelope. Members of the endomembrane system pass materials through each other or though the use of vesicles. GO:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
