Question

17 On a separate sheet of paper, answer the following ques- tions as assigned by your instructor: 1. What are the end products of anaerobic and aerobic respiration pathways? How do those end products compare in energy content and cellular toxicity? 2. How did anaerobic and aerobic yeast cultures differ in rates of CO2 and ethanol production? Do aerobic yeast produce some ethanol and if so, why? 3. Turn in your graph of the data in table 7.3 with this summary. What conclusions about the effect of cold treatment on your study species can you draw from that graph? 4. What are the advantages of aerobic respiration over anaerobic respiration? What are the advantages of anaerobic respiration over aerobic?

Explanation / Answer

1) The end products of aerobic respiration are water, carbon dioxide and ATP. In anaerobic respiration, the end products are lactic acid and ATP. Lactate is more toxic than carbon dioxide which can be expired during respiration. Aerobic respiration produces more energy than anaerobic respiration.
