Question
Chapter 31, Problem 31P
Interpretation Introduction
Interpretation:
Four main components that are required for the translocation of proteins across the ER membrane should be determined.
Concept introduction:
The endomembrane system is composed of ER, Golgi bodies, lysosomes, secretory vesicles, and endosomes. These cellular components are involved in the transport of proteins to the outside of the cell or the other organelles of the cell. Once the protein enters the ER, it never returns to the cytosol. It is carried away by the vesicles to other cellular compartments.
