Which statement should be categorized only in the aerobic section of a Venn diagram comparing aerobic and anaerobic respiration?

• A. Produces ATP through glycolysis
• B. Requires oxygen as a final electron acceptor
• C. Generates lactic acid as a byproduct
• D. Occurs in the cytoplasm

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the difference between aerobic and anaerobic respiration. Aerobic respiration requires oxygen, while anaerobic respiration does not. Both processes produce ATP but differ in their mechanisms and byproducts.
2. Step 2: Analyze the statement 'Produces ATP through glycolysis.' Glycolysis is a process common to both aerobic and anaerobic respiration, so this statement cannot be categorized exclusively in the aerobic section.
3. Step 3: Examine the statement 'Generates lactic acid as a byproduct.' Lactic acid is a byproduct of anaerobic respiration in certain organisms, so this statement belongs in the anaerobic section, not the aerobic section.
4. Step 4: Evaluate the statement 'Occurs in the cytoplasm.' Both aerobic and anaerobic respiration begin with glycolysis, which occurs in the cytoplasm. Therefore, this statement is not exclusive to aerobic respiration.
5. Step 5: Focus on the statement 'Requires oxygen as a final electron acceptor.' This is a defining characteristic of aerobic respiration, as oxygen is essential for the electron transport chain in aerobic processes. This statement should be categorized only in the aerobic section of the Venn diagram.
