Question

End product of fermentation of sugars is

• A. Water and carbon dioxide
• B. Alcohol and carbon dioxide
• C. Carbon dioxide
• D. Alcohol

Answer 1

Answer: (B)

Alcohol and carbon dioxide

Fermentation is a type of anaerobic respiration in which the glucose is broken down into pyruvic acid in the absence of oxygen. During fermentation of sugars, this pyruvic acids coverts to a 2C acetaldehyde and then to ethanol and CO₂. All this takes place in the cytoplasm.

So, the correct option is 'Alcohol and carbon dioxide'
