Detailed explanation-1: -Ethyl alcohol and lactic acid are the products formed by the anaerobic respiration.
Detailed explanation-2: -Anaerobic respiration occurs in the absence of oxygen and is less efficient than aerobic respiration. Unlike aerobic respiration, the end products here are ethyl alcohol as in yeasts and lactic acid as in animal cells. So the answer is ‘Alcohol and lactic acid’.
Detailed explanation-3: -Ethanol is produced by anaerobic fermentation of glucose by Saccharomyces cerevisiae.
Detailed explanation-4: -Anaerobic respiration occurs in the absence of oxygen, as it only requires glucose. In animal cells and some bacterial cells, anaerobic respiration produces lactic acid. In yeast and plant cells, anaerobic respiration produces ethanol and carbon dioxide.
