Exemplar Problems

Question:

Explain the differences between aerobic and anaerobic respiration.

Answer:

  • Aerobic Respiration:

    • Requires oxygen as the final electron acceptor in the electron transport chain.

    • Occurs in the presence of oxygen.

    • Yields a large amount of ATP (up to 38 ATP per glucose molecule).

    • Involves glycolysis, the citric acid cycle, and the electron transport chain.

  • Anaerobic Respiration:

    • Does not require oxygen as the final electron acceptor.

    • Occurs in the absence of oxygen or in low-oxygen conditions.

    • Yields fewer ATP molecules compared to aerobic respiration.

    • Involves glycolysis and different pathways like lactic acid or alcoholic fermentation.
