The enzyme that converts glucose to ethyl alcohol is :
(1) Invertase
(2) Maltase
(3) Zymase
(4) Diastase
Answer: (3) The fermentation of sugar into ethanol is one of the earliest biotechnologies employed by humanity. Fermentation of fermentable sugars by suitable yeast produces ethanol (ethyl alcohol). Yeast is a single-celled fungus containing several enzymes useful during fermentation. Brewer's yeast and wine yeast, for example, contain zymase, an enzyme that can convert glucose to ethanol.
