Question

Describe the pathway a secreted protein takes within a eukaryotic cell, from its production until it is secreted out.

Answer 1

In Eukaryotic cells, proteins are synthesized in the Rough Endoplasmic Reticulum(RER) and then transported to Golgi apparatus. in the Golgi apparatus the proteins are sorted before being sent to the lysosomes, secretory vesicles and the plasma membrane. Transportation of the proteins is necessitated by the vesicles which bud from one compartment and fuse to subsequent compartments.
