alleryAnaerobic respiration in yeast produces
ALactic acid and water as products
BEthanol and carbon dioxide
CPyruvate and oxygen as products
DMethane and hydrogen as products
Answer & Solution
Correct answer: B. Ethanol and carbon dioxide
1. The chapter contrasts aerobic and anaerobic respiration.
2. Yeast performs alcoholic fermentation in the absence of oxygen.
3. It splits glucose into ethanol and CO2.
4. So option A is correct.
