The following one is smallest:
Correct answer: B. Glycine
- A. Maltose
- B. Glycine
- C. Cellulose
- D. Cellobiose
Explanation
The correct answer is Glycine. Glycine is the smallest molecule among the options provided because it is a single amino acid, the basic building block of proteins, and is composed of just two carbon atoms. In contrast, maltose and cellobiose are disaccharides, each made up of two glucose molecules, which makes them larger in size. Cellulose is a polysaccharide made up of long chains of glucose units, making it significantly larger than glycine.

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.
