A good example would be the oxidation of glucose (a monosaccharide) in aerobic respiration.
We distinguish between obligate aerobes and facultative aerobes: obligate aerobes require oxygen, while facultative aerobes can use oxygen, but also have other options.
Almost all animals, most fungi and several bacteria are obligate aerobes. Being an obligate aerobe, although being advantageous from the energetical point of view, means also obligatory facing high levels of oxydative stress[?].
Yeast is an example of a facultative aerobe. Individual human cells are also facultative aerobes: they switch to lactic acid fermentation if oxygen is not available. However, for the whole organism this cannot be sustained for long, and humans are therefore obligate aerobes.
