BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The factor that does not alter the rate hydrolysis of maltose is the number of enzyme molecules present. Enzymes are biological catalysts that promote various reactions in the body. Enzymes are specific in their action. Therefore, only an enzyme can catalyze a particular reaction.

Detailed explanation-2: -Maltose is produced by the enzymatic hydrolysis of starch (a homopolysaccharide) catalyzed by the enzyme amylase. Maltose is further hydrolyzed by the enzyme maltase to produce two molecules of d-glucose.

Detailed explanation-3: -The hydrolysis reaction of maltose in the presence of an acid catalyst gives two molecules – alpha D-glucose. There is a free anomeric carbon present in the structure of maltose which can undergo mutarotation in solution. The resultant solution will be a mixture of alpha and beta maltose.

Detailed explanation-4: -maltase, enzyme that catalyzes the hydrolysis of the disaccharide maltose to the simple sugar glucose.

Detailed explanation-5: -The smallest substrate, maltose, is composed of two glucosyl units, whereas the largest substrate, maltoheptaose, contains seven glucosyl units (5, 14). Closely related carbohydrates, such as glucose, lactose, sucrose, isomaltose, and cellobiose, are not recognized by the maltose transport system (Fig.
