Question

Identify the end product(s) of fermentation from the given options.

• A. Vinegar
• B. Lactic acid
• C. Alcohol
• D. All the above

Answer 1

The correct option is D All the above

Fermentation is the process in which pyruvic acid that is produced by glycolysis is converted into other organic acids or alcohols in the absence of oxygen. Vinegar is produced by bacteria, lactic acid is produced by muscle cells and alcohol is produced by yeast in the absence of oxygen by the process of fermentation. Hence, vinegar, lactic acid and alcohol can be end products of fermentation.
