Anaerobic respiration differs from aerobic respiration by the production of
less amount of energy and water
greater amount of energy and alcohol
less amount of energy and alcohol
greater amount of energy and water
คำอธิบาย
The correct answer is C. Less amount of energy and alcohol.
Anaerobic respiration occurs without oxygen (O₂), whereas aerobic respiration occurs with oxygen. The main differences between the two processes are:
- Energy yield: Anaerobic respiration produces less energy (2 ATP molecules) compared to aerobic respiration (36-38 ATP molecules).
- End products: Anaerobic respiration produces ethanol (alcohol) and carbon dioxide (CO₂) as end products, whereas aerobic respiration produces carbon dioxide and water.
The other options are not correct:
A. Anaerobic respiration produces less energy and alcohol, not water.
B. Anaerobic respiration produces less energy, not greater energy.
D. Anaerobic respiration produces alcohol, not water.
