Electron Acceptors

Some articles on electron acceptors, electron, electron acceptor:

Electron Transport Chains in Bacteria - Electron Acceptors
... Just as there are a number of different electron donors (organic matter in organotrophs, inorganic matter in lithotrophs), there are a number of different electron acceptors, both organic and inorganic ... If oxygen is available, it is invariably used as the terminal electron acceptor, because it generates the greatest Gibbs free energy change and produces the most energy ... In anaerobic environments, different electron acceptors are used, including nitrate, nitrite, ferric iron, sulfate, carbon dioxide, and small organic molecules such as fumarate ...
Bacterial Diseases - Metabolism
... of energy used for growth, the source of carbon, and the electron donors used for growth ... An additional criterion of respiratory microorganisms are the electron acceptors used for aerobic or anaerobic respiration ... for energy, which are mostly oxidised at the expense of oxygen or alternative electron acceptors (aerobic/anaerobic respiration) ...
Biochemistry of Methanogenesis - Importance in Carbon Cycle
... During the decay process, electron acceptors (such as oxygen, ferric iron, sulfate, and nitrate) become depleted, while hydrogen (H2) and carbon dioxide accumulate ... During advanced stages of organic decay, all electron acceptors become depleted except carbon dioxide ... a product of most catabolic processes, so it is not depleted like other potential electron acceptors ...
