Question

Which of the following statement holds true in case of anaerobic respiration?

• A. Anaerobic respiration happens in case of absence of oxygen.
• B. Anaerobic respiration happens in case of less availability of oxygen.
• C. Anaerobic respiration yields ATP.
• D. All of the above

Answer 1

Answer: (D)

All of the above

A. Anaerobic respiration involves the breakdown of food into alcohol and carbon dioxide in the absence of oxygen in many bacteria and yeast.

B. Anaerobic respiration also happens in cases where there is less supply of oxygen. eg. lactic acid synthesis in muscles during strenuous exercises.

C. Aerobic respiration is far more energy-efficient than anaerobic respiration. Aerobic processes produce up to 38 ATP per glucose. Anaerobic processes yield only 2 ATP per glucose.

D. So the correct answer is 'All of the above'.
