The enzyme that catalyses the conversion of glucose te ethanol and carbon (IV) oxide is

The enzyme that catalyzes the conversion of glucose to ethanol and carbon dioxide is called zymase. Zymase is a complex of enzymes that are found in yeast cells and are involved in the fermentation of glucose into ethanol and carbon dioxide. The process of fermentation involves the breakdown of glucose into pyruvate, which is then converted into ethanol and carbon dioxide by the action of zymase. During the fermentation process, zymase catalyzes two important reactions: the conversion of glucose to pyruvate by the action of the enzyme hexokinase, and the conversion of pyruvate to ethanol and carbon dioxide by the action of the enzymes pyruvate decarboxylase and alcohol dehydrogenase. Therefore, the correct option is "zymase" because it is the enzyme complex that is responsible for the conversion of glucose to ethanol and carbon dioxide. The other options are incorrect because diastase and maltase are enzymes involved in the breakdown of carbohydrates into simpler sugars, while ptyalin is an enzyme found in saliva that helps to break down starch into maltose.
