Why do strict anaerobes die in the presence of oxygen?

Question

Quizplus · Accepted Answer

Strict anaerobes lack the necessary enzymes to detoxify reactive oxygen species, which are highly toxic to these organisms. When exposed to oxygen, reactive oxygen species are produced, leading to cell damage and death. Therefore, strict anaerobes cannot survive in the presence of oxygen. Choices B and C are incorrect because strict anaerobes obtain energy through fermentation, not by using oxygen as a terminal electron acceptor. Choice D is incorrect as it contradicts the accepted scientific understanding of strict anaerobes.
