Question

Enzyme that changes glucose to ethyl alcohol is
(A) Zymase
(B) Diastase
(C) Invertase
(D) Maltase

Answer 1

It converts glucose into ethanol through the process of fermentation. It is found naturally in the yeasts and its activity is highly dependent on the type of yeast strains.

Complete answer:
Usually, zymase enzymes help in the breakdown of complex sugar moieties in simpler alcohols with release of carbon dioxide. The diastase enzyme catalyzes the transformation of starch into maltose. Invertase enzyme causes the alteration of sucrose into simpler fructose and glucose molecules. The maltase helps in the breakdown of maltose into glucose molecules. This enzyme is mostly obtained from the plants, bacteria, and yeasts, and also in human beings as well as in vertebrates. It is very important to notice that each variety of enzymes have their significance in conversion of the complex molecules into simpler molecules through the biochemical reactions. The enzymes are much precise because each type of different enzymes has their specifically shaped active sites. The shape of the active site of an enzyme is complementary to the shape of its definite substrate/s. This causes perfection in their fitting with the specific moiety. Zymase converts glucose into ethanol through the process of fermentation. It is found naturally in the yeasts and its activity is highly dependent on the type of yeast strains.

Hence, the correct answer is option ‘A’.

Note: Zymase is also famous as a brand name of the drug pancrelipase. Invertase enzymes are highly used in the candy-production industries. It is frequently derived from the yeasts. Diastase enzyme is usually found in the malt, milk, barley seeds, plants, and also in human saliva. It regulates the proper digestion of carbohydrates in the body. Moreover, there are two main enzymes that are present in yeasts, the maltase and invertase enzymes.
