Single Choice

the disaccharides A,B and C respectively are:

Alactose, sucrose, maltose
Bsucrose, maltose, lactose
Correct Answer
Csucrose, lactose, maltose
Dmaltose, sucrose, lactose

Solution

(A) Sucrose is made up of $$\text{glucose and fructose molecules.}$$ When sucrose is consumed or hydrolyzed the enzyme separates sucrose into its individual sugar units of glucose and fructose.

$$\text{sucrose}\xrightarrow{\text{Hydrolysis}}\text{glucose + fructose}$$


(B) Maltose is made up of $$\text{two molecules of glucose.}$$ and on hydrolysis give two molecules of glucose.

$$\text{maltose}\xrightarrow{\text{Hydrolysis}}\text{glucose + glucose}$$


(C) Lactose is a disaccharide, a type of sugar composed of two simple sugars, $$\text{glucose and galactose. }$$

$$\text{lactose}\xrightarrow{\text{Hydrolysis}}\text{glucose + galactose}$$


Option B is correct.
