which of the following types of orgnisms possess the enzyme catalase?

A) obligate aerobe

B) obligate anaerobe

C) facultative anaerobe

D) both A & B

Solution

answer is A.

obligate aerobes are able to use oxygen as terminal electron acceptor during respiration contain catalase.

obligate anaerobes even though possess catalase, it is very rare and in less quantities. facultative anaerobes which ferment and does not respire using oxygen are also catalase negative. facultative anaerobes under aerobic conditions possess catalase for aerobic respiration
