The products of hydrolysis of lactose are: a. glucose and galactose b. glucose and fructose c. galactose and ribose d. fructose and galactose 4. Which is the most important carbohydrate fuel in human cells? a. ribose b. glucose c. fructose d. galactose 5. Which two monosaccharides combine to form sucrose? a. C-glucose and B-fructose b. a-fructose and a-ribose C. L-glucose and B-glucose d. a-galactose and a-fructose 6. The type of reaction that occurs when a disaccharide is formed from two monosaccharides is a. condensation b. addition c. hydrolysis d. reduction

Answer 1

1.starch is made from two a-glucose linked to one another through glycosidic linkage Ans option b 2. two disacharides are linked through gycosidic bond. Ans option d 3. lactose is made up of glucose and galactose. So therefore on hydrolysis of lactose gives glucose and galactose. Ans option a 4. most important carbohydrate in human cells is glucose Ans option b 5. a-glucose and B-fructose combine to form sucrose Ans option a 6. condensation reaction between two mono sacharides gives a disaccharide Ans option a
