Answer:
As the pathway is not given, lets discuss the pathway of the endomembrane system generally.
Step-by-step explanation:
The endomembrane system comprises of the organelles which modify and package those proteins which have to be transported outside of a cell.
The Endoplasmic reticulum (ER) is a part of this system which helps in the modification of proteins.
The Golgi Apparatus is the part where the packaging of the proteins takes place so that they can be transported outside of the cell.
Certain vesicles then carry these proteins to the cell membrane where they are transported outside of the cell.
