Question

An obligate anaerobe is an organism that would die in an oxygenated environment. What could be assumed about these organisms?

A.) They can’t create ATP (adenosine triphosphate).
B.) They must create their own energy.
C.) They perform only anaerobic respiration.
D.) They perform both aerobic and anaerobic respiration.

Answer 1

They perform only anaerobic respiration.

Step-by-step explanation:

Anaerobic respiration is a form of cellular respiration that produces energy but occurs in the absence of oxygen. So, organisms that are intolerant to oxygen use the anaerobic pathway to obtain the energy needed to sustain life.

Answer 2

The correct option is C.
Obligate anaerobes are micro organisms that are poisoned and killed when exposed to the normal atmospheric oxygen concentration. These organisms can only survive in the absences of oxygen, therefore, they carry out only anaerobic form of respiration in order to obtain the energy that they need.
