How is anaerobic respiration different from aerobic respiration?

• A. Anaerobic respiration occurs in the mitochondria, while aerobic respiration occurs in the cytoplasm.
• B. Anaerobic respiration uses carbon dioxide as the final electron acceptor, while aerobic respiration uses oxygen.
• C. Anaerobic respiration occurs without oxygen, while aerobic respiration requires oxygen.
• D. Anaerobic respiration produces more ATP than aerobic respiration.

Answer: (C)

Verified step by step guidance

1. Understand the basic definitions: Aerobic respiration is a process that requires oxygen to produce energy, while anaerobic respiration does not require oxygen.
2. Identify the location of each process: Aerobic respiration primarily occurs in the mitochondria, whereas anaerobic respiration occurs in the cytoplasm.
3. Determine the final electron acceptor: In aerobic respiration, oxygen acts as the final electron acceptor. In anaerobic respiration, other molecules such as nitrate or sulfate can serve this role, but not oxygen.
4. Compare ATP production: Aerobic respiration is more efficient and produces more ATP compared to anaerobic respiration, which generates less ATP per glucose molecule.
5. Clarify the conditions under which each process occurs: Aerobic respiration occurs in environments with sufficient oxygen, while anaerobic respiration takes place in low or no oxygen conditions.
