Which of the following statements about anaerobic respiration is false?

• A. Anaerobic respiration uses an electron transport chain with a final electron acceptor other than oxygen.
• B. Anaerobic respiration generates more ATP per glucose molecule than aerobic respiration.
• C. Nitrate or sulfate can serve as terminal electron acceptors in anaerobic respiration.
• D. Anaerobic respiration occurs in some prokaryotes.

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the definition of anaerobic respiration. Anaerobic respiration is a type of cellular respiration that uses an electron transport chain but does not use oxygen as the final electron acceptor.
2. Step 2: Identify the role of the final electron acceptor in anaerobic respiration. Unlike aerobic respiration, which uses oxygen, anaerobic respiration uses other molecules such as nitrate, sulfate, or carbon dioxide as terminal electron acceptors.
3. Step 3: Compare ATP yield between aerobic and anaerobic respiration. Aerobic respiration generally produces more ATP per glucose molecule because oxygen is a highly efficient final electron acceptor, whereas anaerobic respiration produces less ATP due to less efficient electron acceptors.
4. Step 4: Recognize which organisms perform anaerobic respiration. Many prokaryotes, including certain bacteria and archaea, are capable of anaerobic respiration, especially in oxygen-limited environments.
5. Step 5: Evaluate the statements given in the problem by applying the above concepts to identify which statement is false, focusing on the ATP yield comparison.
