Question

Denaturation of protein leads to loss of its biological activity by?

• A. formation of amino acids
• B. loss of primary structure
• C. loss of both primary and secondary structure
• D. loss of both secondary and tertiary structures

Answer 1

The correct option is D loss of both secondary and tertiary structures

(D) loss of both secondary and tertiary structures

Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures. Since denaturation reactions are not strong enough to break the peptide bonds, the primary structure remains the same after a denaturation process.
