Why is less energy obtained in anaerobic respiration?
Answer and explanation
Correct answer: Because glucose breaks down incompletely
The governing concept is incomplete oxidation of glucose. Anaerobic respiration occurs without sufficient oxygen, so glucose is only partially broken down into products such as lactic acid in muscles or alcohol and carbon dioxide in yeast. Because much chemical energy remains in these products, less energy is released. Option A is correct; B contradicts anaerobic conditions, while C and D are false.
