Denaturation of protein;
Correct answer: B. Disrupts the secondary and tertiary structures only
- A. Disrupts the primary or secondary or tertiary structure of protein
- B. Disrupts the secondary and tertiary structures only
- C. Disrupts all the primary, secondary and tertiary and even the quaternary structure of protein
- D. Will not affect the original biological activity
Explanation
Denaturation can disrupt the secondary and tertiary structures of a protein. The secondary structure refers to the local folding patterns of the protein, such as alpha-helices and beta-sheets, which are stabilized by hydrogen bonds. Denaturation can break these hydrogen bonds, resulting in the loss of secondary structure.

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.

Haemoglobin is a protein present in blood and helps in transportation of oxygen. It is made up of four chains, two alpha and two beta chains. Myoglobin is another protein similar to haemoglobin. It is present in muscle cells and helps in storage of oxygen. Identify the correct structures of haemoglobin and myoglobin respectively:
