Which statement about anaerobic respiration is true?

• A. Anaerobic respiration occurs only in plant cells.

• D. Anaerobic respiration results in the complete oxidation of glucose to carbon dioxide and water.

Answer: (C)

Verified step by step guidance

1. Understand the concept of anaerobic respiration: Anaerobic respiration is a type of cellular respiration that occurs without oxygen. It is used by certain organisms or cells when oxygen is unavailable or in limited supply.
2. Compare anaerobic respiration to aerobic respiration: Aerobic respiration requires oxygen and produces more ATP per glucose molecule, while anaerobic respiration produces less ATP and does not require oxygen.
3. Analyze the statement 'Anaerobic respiration occurs only in plant cells': This is incorrect because anaerobic respiration occurs in various organisms, including animals, bacteria, and yeast, not just plants.
4. Evaluate the statement 'Anaerobic respiration produces more ATP per glucose molecule than aerobic respiration': This is incorrect because aerobic respiration produces significantly more ATP (approximately 36-38 ATP per glucose molecule) compared to anaerobic respiration (approximately 2 ATP per glucose molecule).
5. Confirm the correct statement: 'Anaerobic respiration does not require oxygen to produce ATP' is true because the process relies on pathways like glycolysis and fermentation, which do not involve oxygen.
