Hydrolysis of glycogen gives:
Correct answer: A. Glucose
- A. Glucose
- B. Galactose
- C. Fructose
- D. Ribose
Explanation
Glycogen is a storage form of energy in animals and is made up of repeating glucose units linked by a-1,4-glycosidic and a-1,6-glycosidic bonds. During hydrolysis, water is used to break these bonds, releasing glucose molecules. Therefore, the hydrolysis of glycogen yields glucose. The other sugars listed (galactose, fructose, and ribose) are not components of glycogen, thus they are not products of its hydrolysis.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
