Multiple choice

Why is aerobic respiration more advantageous than anaerobic respiration?

  1. Because it requires oxygen

  2. Because it produces more energy.

  3. Because it causes complete break down of respiratory substrate.

  4. Because it produces water.

B Correct answer
Explanation

Aerobic respiration produces approximately 36-38 ATP molecules per glucose molecule, whereas anaerobic respiration yields only 2 ATP. This 18-fold difference in energy yield makes aerobic respiration far more advantageous for organisms. Option C is incorrect because both processes cause complete breakdown - anaerobic also fully breaks down glucose (to lactate/ethanol).
