Question

Match the type of bacterium to examples

Answer 1

Facultative aerobic bacteria do not require oxygen but can survive in the presence of oxygen (generate ATP by aerobic respiration). Whereas facultative anaerobic bacteria require oxygen but can survive in the absence of oxygen (generate ATP by fermentation). Obligate aerobes need oxygen because they cannot ferment or respire anaerobically whereas, obligate anaerobes are organisms that cannot grow in the presence of oxygen.

So the correct option is 'A-2, B-1,C-4,D-3'.
