Which pathway correctly traces a secreted protein?
A.Rough ER → Golgi → vesicle → plasma membrane
B.Nucleus → lysosome → Golgi
C.Golgi → rough ER → mitochondria
D.Smooth ER → ribosome → vacuole
Explanation
Core Concept
Ribosomes on the rough ER make the protein into the ER lumen; vesicles carry it to the Golgi for processing, then secretory vesicles fuse with the membrane to release it.
Correct Answer
ARough ER → Golgi → vesicle → plasma membrane
