Acetic acid bacteria have aerobic respiratory metabolism, and oxygen is generally used as the final electron acceptor; however, other compounds may occasionally act as final electron acceptors, allowing the bacteria to survive under nearly anaerobic conditions, such as the ones present during wine fermentation .
Certain prokaryotes, including some species of bacteria and Archaea, use anaerobic respiration. For example, the group of Archaea called methanogens reduces carbon dioxide to methane to oxidize NADH.In fermentation, the distance between the pyruvate and the final electron acceptor is shorter and therefore not as much energy is produced. Asked in Atoms and Atomic Structure , Chlamydia Does ... Oxygen serves as the final electron acceptor of the electron transport chain. Not hydrogen. Asked in Chemistry , Elements and Compounds , Atoms and Atomic StructureAn electron acceptor is a chemical entity that accepts electrons transferred to it from another compound. It is an oxidizing agent that, by virtue of its accepting electrons, is itself reduced in the process. Electron acceptors are sometimes mistakenly called electron receptors. There is class of oxidoreductases called oxygenases which incorporate molecular oxygen into the substrates and not just use it as an electron acceptor like in oxidases (note that the terminal enzyme in ETC is an oxidase and there are other such oxidases). In other words, oxygen is not a cofactor but a co-substrate. Oct 06, 2017 · The final electron acceptor is not the molecular oxygen as in aerobic respiration. Different types of organisms use different types of final electron acceptors. These can be sulfate ions, nitrate ions or carbon dioxide. Methanogenic bacteria are one such type of organisms that use carbon dioxide as the final electron acceptor in the absence of ...
