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
The Correct Option is B
Solution and Explanation
Step 1: To find the exception, recall the basic identity of chaperones: they are a class of proteins, found across species from bacteria to humans, dedicated to quality control of protein folding.
Step 2: Being proteins, they cannot be lipid in nature. This directly marks option b as the incorrect statement.
Step 3: The remaining statements are accurate. Chaperones bind hydrophobic patches of incompletely folded proteins to promote correct folding and block aggregation, and they carry out an editing or quality-control role.
Step 4: Their function is powered by ATP, so they show ATPase activity, and a large subset are the inducible heat shock proteins. Thus a, c and d are true while b is the false one.
\[\boxed{\text{Are lipid in nature}}\]
