What is the sequence of events in the endomembrane system for a protein intended for export?
Understand the Problem
The question is asking about the correct order of events that occur in the endomembrane system for a protein that is meant to be exported from a cell. It lists multiple choices that outline different pathways a protein may take, and we need to identify which one follows the correct biological sequence.
Answer
rough ER → Golgi → secretory vesicles → cell exterior
The final answer is rough ER → Golgi → secretory vesicles → cell exterior
Answer for screen readers
The final answer is rough ER → Golgi → secretory vesicles → cell exterior
More Information
Proteins intended for export follow the secretory pathway, which involves synthesis on the rough endoplasmic reticulum (ER), modification and sorting in the Golgi apparatus, and transportation via secretory vesicles to the cell exterior.
Tips
A common mistake is to confuse the process for proteins destined for the lysosome instead of export; they take a different path in the endomembrane system.
