The process of fermentation of starch involves many enzymes; the sequence of enzymes used are:
Correct answer: C. Maltase-diastase-zymase
- A. Diastase-maltase-zymase
- B. Zymase-maltase-diastase
- C. Maltase-diastase-zymase
- D. Diastase-zymase-maltase
Explanation
The fermentation of starch involves a series of enzymes, typically including α-amylase, maltase, and zymase. Among the options provided, the correct sequence of enzymes used in the fermentation of starch is:(c) Maltase-diastase-zymaseHere's why:Maltase: Maltase catalyzes the hydrolysis of maltose into two molecules of glucose. Maltose is one of the products of the initial breakdown of starch by α-amylase.Diastase (α-amylase): Diastase, or α-amylase, is responsible for breaking down starch into shorter chains of glucose molecules, maltose, and some glucose. It initiates the breakdown of starch into fermentable sugars.Zymase: Zymase is a complex mixture of enzymes found in yeast cells. It catalyzes the fermentation of glucose and other sugars into ethanol (alcohol) and carbon dioxide (CO2) during the process of alcoholic fermentation.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
