Which of the following cannot be hydrolyzed?
Correct answer: B. Monosaccharides
- A. Polysaccharides
- B. Monosaccharides
- C. Oligosaccharides
- D. Sucrose
Explanation
The correct answer is monosaccharides. Monosaccharides, such as glucose and fructose, are the simplest form of carbohydrates and cannot be broken down into simpler sugars through hydrolysis. In contrast, polysaccharides are complex carbohydrates that consist of multiple monosaccharide units and can be hydrolyzed into simpler sugars. Oligosaccharides, being composed of a few monosaccharide residues, can also be hydrolyzed. Similarly, sucrose, a disaccharide, can be hydrolysed into glucose and fructose.

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.
