Correct Answer: Zymase

Solution : The correct option is zymase.

Zymase is an enzyme complex present in yeast cells that plays an important part in the fermentation process. It catalyses the transformation of glucose and fructose (simple sugars) into ethanol (alcohol) and CO2. This biochemical reaction is essential in the manufacture of alcoholic drinks such as beer, wine, and spirits, as well as in a variety of industrial operations such as the manufacturing of biofuels and certain chemicals.
