Question

The enzyme which converts glucose to ethyl alcohol is:

• A. zymase
• B. invertase
• C. maltase
• D. diastase

Answer 1

The correct option is A zymase

Zymase is an enzyme complex that catalyzes the fermentation of sugar into ethanol and carbon dioxide. It occurs naturally in yeasts. the reaction is as follow:
$\underset{\text{Glucose or Fructose}}{C_6{H}_{12}{O}_6}\underset{\text{in yeast}}{\overset{\text{Zymase}}{\to }}\underset{\text{Ethanol}}{2C_2{H}_{5}OH}+\underset{\text{Carbon dioxide}}{2C{O}_2}$
Hence correct option is a.
