    • C. 4
    • D. 30

  2. 2. What is the main role of converting pyruvate to lactate?

    • A. To make ATP
    • B. To oxidise reduced NAD so glycolysis can continue
    • C. To produce carbon dioxide
    • D. To store glucose

  3. 3. Which products form from pyruvate in anaerobic respiration in plants?

    • A. Lactate only
    • B. Ethanol only
    • C. Water and carbon dioxide
    • D. Ethanol and carbon dioxide

  4. 4. In a respirometer, why is carbon dioxide absorbed?

    • A. To speed up respiration
    • B. To keep the organisms alive
    • C. So that the volume change shows oxygen uptake only
    • D. To cool the organisms

  5. 5. Why does lactate build-up cause muscle fatigue?

    • A. It raises the pH of muscle cells
    • B. It makes more actin
    • C. It increases the oxygen supply
    • D. It lowers pH, which alters enzyme shape and reduces ATP supply
