Question

Quizplus · Accepted Answer

The folding and unfolding of polypeptides in a cell is a complex process, and it often requires the assistance of chaperones (proteins that aid in protein folding). Chaperones can help to prevent protein aggregation, proteolysis, and other potentially harmful interactions that can occur during the folding process. Lysosomes are involved in the breakdown of cellular waste and are not directly involved in protein folding. Ribosomes are responsible for the synthesis of proteins, but they do not play a role in protein folding after synthesis. Prosthetic groups are non-protein molecules that are covalently attached to proteins, and they do not directly influence protein folding.
