Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which monosaccharide is the disaccharide maltose then broken down into?
A
Galactose + Glucose
B
Fructose + Glucose
C
Sucrose + Glucose
D
Glucose + Glucose
Explanation: 

Detailed explanation-1: -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. The monosaccharide unit on the left is the hemiacetal of the -d-glucopyranosyl unit.

Detailed explanation-2: -Maltose is converted to two molecules of glucose by the enzyme maltase, which hydrolyzes the glycosidic bond.

Detailed explanation-3: -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).

Detailed explanation-4: -Maltase is the intestinal enzyme of the human body that catalyzes the hydrolysis of the disaccharide maltose to the simple sugar glucose molecules.

Detailed explanation-5: -Maltose is composed of two molecules of glucose while sucrose is made up of one molecule of glucose and another one is fructose which is also a monosaccharide.
