GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. GO:0008863 Catalysis of the reaction: formate + NAD+ = CO2 + NADH. 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:0009326 An enzyme complex that catalyzes the dehydrogenation of formate to produce carbon dioxide (CO2). GO:0045333 The enzymatic release of energy from inorganic and organic compounds (especially carbohydrates and fats) which either requires oxygen (aerobic respiration) or does not (anaerobic respiration). GO:0009055 A molecular function representing the directed movement of electrons from one molecular entity to another, typically mediated by electron carriers or acceptors, resulting in the transfer of energy and/or the reduction-oxidation (redox) transformation of chemical species. This activity is fundamental to various biological processes, including cellular respiration and photosynthesis, as well as numerous enzymatic reactions involved in metabolic pathways.
