Question

Oxygen kills some prokaryotes, like __________, even briefly.

a) Obligate anaerobes
b) Facultative aerobes
c) Obligate aerobes
d) Aerotolerant organisms

Answer 1

Oxygen kills some prokaryotes, like Obligate anaerobes, even briefly. Therefore, the correct answer is c) Obligate anaerobes.

Step-by-step explanation:

Oxygen kills some prokaryotes, like Obligate anaerobes, even briefly.

An anaerobic organism is any organism that does not need oxygen for growth and even dies in its presence. Obligate anaerobes will die when exposed to atmospheric levels of oxygen. Clostridium perfringens bacteria, which are commonly found in soil around the world, are obligate anaerobes. Infection of a wound by C. perfringens bacteria causes the disease gas gangrene. Obligate anaerobes use molecules other than oxygen as terminal electron acceptors.

Therefore, the correct answer is c) Obligate anaerobes.
