Carbohydrates are classified into:
Correct answer: A. Three main groups
- A. Three main groups
- B. Seven distinct groups
- C. Three to seven categories
- D. More than seven categories
Explanation
Carbohydrates are primarily classified into three groups: monosaccharides, oligosaccharides, and polysaccharides. Monosaccharides are the simplest form, with a single sugar unit, such as glucose and fructose. Oligosaccharides consist of a small number of sugar units, typically between 2 and 10, like sucrose and lactose. Polysaccharides are more complex carbohydrates with many sugar units, such as starch and cellulose. Options suggesting seven or more groups are incorrect because they do not adhere to the commonly accepted classification system.

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.
