Fermentation results in the production of ______ ATP compared to both aerobic and anaerobic respiration.

• A. less
• B. the same amount of
• C. more
• D. no

Answer: (A)

Verified step by step guidance

1. Step 1: Begin by understanding the process of fermentation. Fermentation is a metabolic pathway that allows cells to produce energy (ATP) in the absence of oxygen. It is an anaerobic process, meaning it does not require oxygen.
2. Step 2: Compare fermentation to aerobic respiration. Aerobic respiration is highly efficient and produces a significant amount of ATP (approximately 36-38 ATP molecules per glucose molecule) because it fully oxidizes glucose using oxygen.
3. Step 3: Compare fermentation to anaerobic respiration. Anaerobic respiration also occurs without oxygen but uses an electron transport chain with a different final electron acceptor (not oxygen). It produces more ATP than fermentation but less than aerobic respiration.
4. Step 4: Analyze the ATP yield of fermentation. Fermentation produces only 2 ATP molecules per glucose molecule, which is significantly less than both aerobic and anaerobic respiration.
5. Step 5: Based on the comparison, conclude that fermentation results in the production of less ATP compared to both aerobic and anaerobic respiration.
