Question

Select the correct statements regarding anaerobic respiration.

• A. Oxygen is absent when this form of respiration takes place.
• B. Lower organisms such as bacteria and yeast use this type of respiration.
• C. Oxygen is present when this form of respiration takes place.
• D. Anaerobic respiration release more energy than aerobic respiration.

Answer 1

Answer: (A), (B)

The correct options are
A

Oxygen is absent when this form of respiration takes place.

B

Lower organisms such as bacteria and yeast use this type of respiration.

Anaerobic means “without air”. Therefore, this type of cellular respiration does not use oxygen to produce energy. Sometimes there is not enough oxygen around for some organisms to respire, but they still need the energy to survive. Due to lack of oxygen, they carry out respiration in the absence of oxygen to produce the energy that they require. Lower organisms such as bacteria and yeast generally use this type of respiration.
