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

Question

Quizplus · Accepted Answer

Proteins synthesized at the endoplasmic reticulum are translocated into the ER lumen, where they become separated from the cytosol. They are then further processed, folded, and modified before being transported to their final destinations, such as the cell membrane or secreted outside the cell. Once they are in the ER lumen, they no longer have access to the cytosol.
