What is the function of molecular chaperones in protein metabolism?

A They facilitate protein folding and prevent aggregation ✓
B They regulate protein degradation by recognizing and targeting misfolded proteins
C They stimulate protein synthesis by recruiting ribosomes to mRNA
D They inhibit protein transport by blocking translocation channels

Explanation

Molecular chaperones, such as Hsp70 and Hsp90, play a crucial role in protein metabolism by facilitating proper protein folding, preventing aggregation, and maintaining protein homeostasis.

Mnemonic

CHAP = Chaperones Help Achieve Proper folding
