Why is more energy obtained in aerobic respiration and less in anaerobic respiration?
Answer and explanation
Correct answer: In aerobic respiration, glucose breaks down more completely.
The governing concept is the completeness of glucose oxidation. In aerobic respiration, oxygen permits glucose to be broken down through multiple stages into carbon dioxide and water, so much of its stored chemical energy is transferred to ATP. Anaerobic pathways break glucose down only partially into products such as lactic acid or alcohol, yielding less ATP, though not zero. Hence option A is correct and D is false.
