Answer 1

Explanation:

Some proteins yielded by gene expression are translocated to the endoplasmatic reticulum (ER).

1. These proteins which entered the ER are synthesized by ribosomes in the rough ER (as protein synthesis is not done by the smooth ER.)
2. Then proteins exit ER inside vesicles.
3. These vesicles carrying proteins travel through the Golgi apparatus cisternae in the cis face. ((entrance face))
4. Proteins enter the secretory vesicle.
5. Proteins exit the Golgi apparatus from the trans face ((exit face)). Then, they exit the plasma membrane, thus the cell.

Importance:
The secretion pathway are the most effective method to 'produce' specialized proteins ready to complete their duties.
