Most polysaccharides are composed of chains of condensed
Correct answer: B. Hexose units
- A. Cellulose units
- B. Hexose units
- C. Pentose units
- D. Sucrose units
Explanation
The correct answer is hexose units. Most polysaccharides are comprised of hexose units like glucose, which is a six-carbon sugar. These hexose sugars link together to form complex carbohydrates such as starch, cellulose, and glycogen. Option A is incorrect because cellulose is itself a polysaccharide and not a basic subunit. Option C is incorrect because pentose units are typically found in nucleic acids rather than polysaccharides. Option D is incorrect because sucrose is a disaccharide, composed of glucose and fructose, and is not a building block of polysaccharides.

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.
