Question

Which among the following is incorrect about denaturation?

(a) Proteins have a unique structure which might get disrupted with change in pH and temperature

(b) Secondary, tertiary and quaternary structure is lost

(c) Proteins still retain their characteristics as they don’t lose their primary structure

(d) Proteins are stereospecific to many enzymes

I got this question during an interview.

My question comes from Biomolecules-2 topic in section Biomolecules of Biology – Class 11

Answer 1

The correct answer is (c) Proteins still retain their characteristics as they don’t lose their primary structure

Best explanation: Proteins have a unique structure which might get disrupted with change in pH and temperature. Denaturation leads to loss of secondary, tertiary and quaternary structure.  Proteins lose their characteristic if their structure is lost. Proteins are stereospecific to many enzymes.
