But some facultative anaerobes appear able to do this. | |

| Jan 19, 2018 at 17:06 | comment | added | David | As it stands this is not the sort of answer this site encourages. See the Help especially the section "Provide context for links". Your answer would be improved by (1) Emphasising that the TCA is intrinsically anaerobic, it is the process of reoxidising NADH that can involve oxygen or not, (2) That for all organisms have a single electron acceptor, in most cases (and in all animals) oxygen. At the moment your answer could be interpreted as certain microbes having a choice of electron acceptor. | |
