Proteins are;
Correct answer: B. Heteropolymer
- A. Homopolymer
- B. Heteropolymer
- C. Homogenous mixture of amino acids
- D. Heterogeneous mixture of amino acids
Explanation
Proteins are considered heteropolymers. A heteropolymer refers to a polymer composed of different types of monomers. In the case of proteins, they are made up of a wide variety of amino acids. There are 20 different types of amino acids commonly found in proteins, each with its own unique chemical properties. These amino acids can be arranged in different sequences within the protein chain, giving rise to the diverse structures and functions of proteins. Therefore, proteins are heteropolymers due to the presence of multiple types of amino acids.

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.
