Which term most appropriately describes catalase, collagen and haemoglobin?
Correct answer: D. Polypeptides
- A. Enzymes
- B. Globular proteins
- C. Fibrous proteins
- D. Polypeptides
Explanation
Option D is correct. The most appropriate term that describes catalase, collagen, and hemoglobin is proteins. Proteins are large molecules that are made up of amino acids. All proteins are made by translation of polypeptides. Since, catalase (enzyme), haemoglobin and collagen are proteins made from polypeptides.

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.
