Question

The incorrect statement about the denaturation of proteins is:

A

It results due to change of temperature and pH.

B

It results in the loss of biological activity of proteins.

C

A protein is formed from amino acids linked by peptide bonds.

D

Uncoiling of the helical structure takes place.

Step-by-Step Solution

Denaturation of proteins is brought about by physical changes (like temperature) or chemical changes (like pH). During denaturation, the secondary and tertiary structures are destroyed, which involves the uncoiling of the helical structure, leading to the loss of the protein's biological activity. However, the primary structure remains intact. The statement 'A protein is formed from amino acids linked by peptide bonds' describes the fundamental primary structure of a protein, but it is not a statement detailing the process or effects of denaturation.

Exam Context & Concepts Covered

This question aligns with the NEET CHEMISTRY syllabus, specifically targeting concepts from Biomolecules. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
