All are true about chaperones except:
All are true about chaperones except:
Show Hint
Chaperones are proteins, not lipids.
Updated On: Jun 24, 2026
- Cause folding of proteins
- Are lipid in nature
- May have ATPase activity
- Include heat shock proteins
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Molecular chaperones are themselves proteins. They help other newly made polypeptides fold correctly without becoming a permanent part of the finished protein. So the statement that they are lipid in nature is false, and that is the exception asked for.
Step 2: Chaperones do assist or ensure proper protein folding and prevent aggregation by binding hydrophobic regions of unfolded proteins, so option a is true.
Step 3: Most chaperones show ATPase activity and bind ATP or ADP, an interaction important for their folding function, so option c is true.
Step 4: Many chaperones are heat shock proteins (Hsp) that are induced when cells face conditions causing protein unfolding, so option d is also true. Hence the only false statement is that they are lipid in nature.
