What are molecular chaperones?
A
3D conformation
B
Speeds up metabolic reactions
C
Bind to short stretches of hydrophobic amino acids to help unfold proteins achieve their proper 3D conformation.
D
binds to a single molecule of oxygen
Explanation: 

Detailed explanation-1: -Known molecular chaperones do not convey steric information essential for correct assembly, but appear to act by binding to interactive protein surfaces that are transiently exposed during various cellular processes; this binding inhibits incorrect interactions that may otherwise produce non-functional structures.

Detailed explanation-2: -1. What are molecular chaperones? Explanation: Molecular chaperones are helper proteins that help unfolded or misfolded polypeptide chains to assume a certain folded state. The role of these proteins is to prevent the proteins from non-selectively interacting with other components in the cell.

Detailed explanation-3: -Chaperones are proteins that guide proteins along the proper pathways for folding. They protect proteins when they are in the process of folding, shielding them from other proteins that might bind and hinder the process.

Detailed explanation-4: -Molecular chaperones are diverse families of multidomain proteins that have evolved to assist nascent proteins to reach their native fold, protect subunits from heat shock during the assembly of complexes, prevent protein aggregation or mediate targeted unfolding and disassembly.
