Proteins synthesized by the endoplasmic reticulum become permanently separated from the cytosol as soon as they have been synthesized.

Question

Quizplus · Accepted Answer

Proteins synthesized by the endoplasmic reticulum are inserted into the ER membrane or transported into the ER lumen, which separates them from the cytosol. Once inside the ER, the proteins undergo further processing and modifications before being transported to their final destination. Therefore, they become permanently separated from the cytosol as soon as they enter the ER.
