Which of the following best describes the difference between anaerobic fermentation and aerobic respiration?

• A. Anaerobic fermentation uses oxygen as the final electron acceptor, while aerobic respiration does not.
• B. Anaerobic fermentation occurs without oxygen, while aerobic respiration requires oxygen.
• C. Anaerobic fermentation occurs in the mitochondria, while aerobic respiration occurs in the cytoplasm.
• D. Anaerobic fermentation produces more ATP than aerobic respiration.

Answer: (B)

Verified step by step guidance

1. Understand the basic definitions: Anaerobic fermentation is a process that occurs without oxygen, while aerobic respiration requires oxygen.
2. Identify the location of each process: Anaerobic fermentation typically occurs in the cytoplasm, whereas aerobic respiration occurs in the mitochondria.
3. Compare the ATP yield: Aerobic respiration generally produces more ATP compared to anaerobic fermentation.
4. Clarify the role of oxygen: In aerobic respiration, oxygen acts as the final electron acceptor, whereas anaerobic fermentation does not use oxygen.
5. Review the options given in the problem and match them with the correct descriptions of anaerobic fermentation and aerobic respiration.
