NEET PG DENTAL EXAM

Detailed explanation-1: -Starch and glycogen are broken down into glucose by amylase and maltase. Sucrose (table sugar) and lactose (milk sugar) are broken down by sucrase and lactase, respectively.

Detailed explanation-2: -Amylases digest starch into smaller molecules, ultimately yielding maltose, which in turn is cleaved into two glucose molecules by maltase.

Detailed explanation-3: -The enzyme amylase breaks glycosidic linkages between glucose monomers only when they are present in alpha form. So, they can easily break the bond between glycogen, starch, and amylopectin, which are polymers of glucose and are used as storage polysaccharides in plants. Thus, the option is correct.

Detailed explanation-4: -During digestion, starch is partially transformed into maltose by the pancreatic or salivary enzymes called amylases; maltase secreted by the intestine then converts maltose into glucose. The glucose so produced is either utilized by the body or stored in the liver as glycogen (animal starch).
