Question

Fermentation products of yeast are

• A. H${}_2$O + CO${}_2$
• B. Methyl alcohol + CO${}_2$
• C. Methyl alcohol + Water
• D. Ethyl alcohol + CO${}_2$

Answer 1

The correct option is D Ethyl alcohol + CO${}_2$

Unicellular organisms like yeast undergo an alternate pathway of respiration in which an organic substrate is broken down in absence of oxygen. The end products are alcohol and CO${}_2$. Such a process is called alcoholic fermentation. In Yeast, the fermentation products are ethyl alcohol and carbon dioxide.

So the answer is 'Ethyl alcohol + CO${}_2$'.
