Explanation:
Detailed explanation-1: -Amylases digest starch into smaller molecules, ultimately yielding maltose, which in turn is cleaved into two glucose molecules by maltase. Starch comprises a significant portion of the typical human diet for most nationalities.
Detailed explanation-2: -Enzymatic conversion of starch to sugars is usually achieved by a two-step process. In the first step, a starch slurry is heated to its gelatinization temperature in the presence of -amylase, to give dextrin, and in the second step, amyloglucosidase (glucoamylase) is used to convert dextrin to glucose.
Detailed explanation-3: -The statement is false. Saliva contains salivary amylase(ptyalin) that converts starch into maltose. Was this answer helpful?
