Question

Which among the following plays a role in the production of alcohol in beer?

• A. Bacteria
• B. Protozoan
• C. Virus
• D. Yeast

Hint:

Yeast is the primary microorganism responsible for fermenting sugars into alcohol during beer production. It is a key player in the brewing process.

Answer 1

The Correct Option is D

In the production of alcohol in beer, yeast plays a crucial role. Yeast is a microorganism that ferments sugars in the wort (the liquid extracted from malted grains) and converts them into alcohol and carbon dioxide. This process is known as fermentation. - Bacteria can sometimes play a role in fermentation, but they are not primarily responsible for alcohol production in beer. - Protozoans and viruses do not contribute to alcohol production in beer. Thus, the correct answer is (d) Yeast.
