Question

Experiment 5 with yeast supported the claim that anaerobic respiration was taking place. The experiment was repeated using unboiled water and without the liquid paraffin. Fermentation still took place and carbon dioxide was produced. Does this mean that the design or the interpretation of the first experiment was wrong? Explain your answer.

Answer 1

No, it does not mean that the interpretation or design of the first experiment was wrong. What it could mean is that using unboiled water or the lack of paraffin was not the catalyst that caused the carbon dioxide to be produced.
