Question

Illustrate obligatory aerobes with an example.

Answer 1

Obligatory aerobes:

1. An obligatory aerobe is a living being that needs oxygen to survive.
2. These organisms use oxygen to metabolize compounds like carbohydrates or fats to obtain energy through cellular respiration.
3. The electron transport chain's terminal electron acceptor is oxygen in this kind of respiration.

Example:

1. Bacillus subtilis bacteria can only breathe aerobically.
2. They are destroyed in anaerobic environments.
