Question

Aerobic respiration is how many times useful than anaerobic respiration?

• A. 2
• B. 8
• C. 19
• D. 38

Answer 1

The correct option is C 19

• The process of aerobic respiration completely metabolizes glucose into carbon dioxide and water generates 38 ATP molecules. On the other hand process of anaerobic respiration incompletely oxidizes glucose into lactic acid or ethyl alcohol and carbon dioxide.
• Only 2 ATP molecules are gained during anaerobic respiration.
• Thus the process of aerobic respiration is 38/ 2 i.e., 19 times more beneficial than anaerobic respiration in terms of ATP yield.
