BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Starch is a polymeric molecule which hydrolyze into smaller units which are simple sugars. Starch is a homo-polysaccharide. Thus, the correct option is 3.

Detailed explanation-2: -When you eat starchy foods, the starches are broken down into sugars, including glucose, maltotriose and maltose, by an enzyme called amylase found in your saliva and small intestine. These compound sugars are further broken down into simple sugars by other enzymes, including maltase, lactase, sucrase and isomaltase.

Detailed explanation-3: -The human digestive process breaks down the starches into glucose units with the aid of enzymes, and those glucose molecules can circulate in the blood stream as an energy source.

Detailed explanation-4: -The long polysaccharide starch is broken down (hydrolyzed) by the enzyme amylase. The products are glucose molecules (a monosaccharide) and maltose (a disaccharide).

Detailed explanation-5: -The breakdown of starch into glucose involves digestive enzymes that are produced by certain glands in the body. First, starch is broken down into disaccharides called maltose. The term disaccharide literally means two sugars, as disaccharides like maltose consist of two simple sugar molecules bound together.
