Superoxide dismutase is indispensable to
A) obligate anaerobes.
B) aerobes.
C) aerotolerant anaerobes.
D) all of the above.

Question

Quizplus · Accepted Answer

Superoxide dismutase is a crucial enzyme for aerobic organisms as it helps protect them against reactive oxygen species (ROS) produced by aerobic respiration. Obligate anaerobes do not perform aerobic respiration and therefore do not produce ROS, while aerotolerant anaerobes can survive in both aerobic and anaerobic conditions and have other mechanisms to combat ROS, so superoxide dismutase is not as critical for their survival.
