Molecular Chaperones Can Work by Creating an "Isolation Chamber

Molecular chaperones can work by creating an "isolation chamber." What is the purpose of this chamber?

A) The chamber acts as a garbage disposal, degrading improperly folded proteins so that they do not interact with properly folded proteins.
B) This chamber is used to increase the local protein concentration, which will help speed up the folding process.
C) This chamber serves to transport unfolded proteins out of the cell.
D) This chamber serves to protect unfolded proteins from interacting with other proteins in the cytosol, until protein folding is completed.
