D)carbohydratase
E)pronases

Question

Quizplus · Accepted Answer

Molecular chaperones are a type of protein that assists in the folding and unfolding of polypeptides, ensuring they reach their correct conformation. Hsp70 (heat shock protein) family chaperones are particularly important in preparing polypeptides for mitochondrial uptake, and they specifically direct mitochondrial proteins to the cytosolic surface of the outer mitochondrial membrane.
