Question

what's the difference between facultative anaerobes and facultative aerobes?​

Answer 1

Answer:

A facultative anaerobe is an organism which can survive in the presence of oxygen, can use oxygen in aerobic respiration, but can also survive without oxygen via fermentation or anaerobic respiration. Most eukaryotes are obligate aerobes, and cannot survive without oxygen.

Answer 2

Answer:

A facultative anaerobe is an organism that makes ATP by aerobic respiration if oxygen is present , but is capable of switching to fermentation or anaerobic respiration if oxygen is absent. An obligate aerobe , by contrast, cannot make ATP in the presence of oxygen.
