Read the passage given below and answer the following questions:
When a protein in its native form, is subjected to physical changes like change in temperature or chemical changes like change in pH, the hydrogen bonds are disturbed. Due to this, globules unfold and helix get uncoiled and protein loses its biological activity. This is called denaturation of protein.
The denaturation causes change in secondary and tertiary structures but primary structures remains intact.
Examples of denaturation of protein are coagulation of egg white on boiling, curding of milk, formation of cheese when an acid is added to milk.
Q. Mark the wrong statement about denaturation of proteins.

Explanation:
The given passage discusses the denaturation of proteins, which refers to the process in which a protein loses its native conformation and biological activity due to physical or chemical changes. The passage states that denaturation causes changes in the secondary and tertiary structures of proteins, but the primary structure remains intact. It also provides examples of protein denaturation, such as coagulation of egg white, curding of milk, and the formation of cheese.
Primary Structure of Protein:
- The primary structure of a protein refers to the linear sequence of amino acids in the polypeptide chain.
- The sequence of amino acids is determined by the genes and is unique to each protein.
- Denaturation does not alter the sequence of amino acids, so the primary structure remains intact.
Secondary and Tertiary Structures:
- Secondary structure refers to the local folding patterns in a protein, commonly held by hydrogen bonds between amino acids.
- Tertiary structure refers to the overall 3D shape of a protein, which is stabilized by various interactions like hydrogen bonds, disulfide bonds, hydrophobic interactions, etc.
- Denaturation disrupts these interactions, leading to the unfolding of globules and uncoiling of helices.
- As a result, the secondary and tertiary structures are altered or destroyed, causing the protein to lose its native conformation.
Incorrect Statement:
The passage states that globular proteins are converted into fibrous proteins during denaturation. However, this statement is incorrect. The correct statement should be that globular proteins are converted into unfolded or denatured proteins, not fibrous proteins.
Examples of Denaturation:
- The coagulation of egg white on boiling is an example of denaturation. Heat disrupts the hydrogen bonds that stabilize the protein, leading to the formation of a solid mass.
- The curding of milk is another example. Acid or enzymes cause the proteins in milk to denature and aggregate, forming curds.
- The formation of cheese when an acid is added to milk is also a denaturation process. The acid causes the proteins in milk to denature and coagulate, resulting in the formation of curds that are used to make cheese.
In conclusion, the incorrect statement in the given passage is that globular proteins are converted into fibrous proteins during denaturation. The primary structure of the protein remains intact, while the secondary and tertiary structures are disrupted, leading to the loss of biological activity.
