Question

The enzyme which converts glucose into ethyl alcohol $\left(C_2{H}_{5}OH\right)$ is

• A. Diastase
• B. Maltase
• C. Zymase
• D. Invertase

Answer 1

Answer: (C)

Zymase

The process which converts glucose into ethyl alcohol with the liberation of carbon dioxide is known as alcoholic fermentation. It is carried out by anaerobic fungus such as yeast. The process occurs in the presence of enzyme zymase which is present in yeast. This method is used in the preparation of alcohol by fermentation of sugars.

C6H12O6+ Zymase → 2 C2H5OH + 2 CO2

Thus, the correct answer is option C.
