How are proteins transported out of the endoplasmic reticulum to the Golgi apparatus?

1 Answer

The synthesized proteins in ER are transported to the golgy bodies through the network of membrane-bound vesicles.

Explanation:

The endoplasmic reticulum and golgi apparatus are network of membranes. Although, they are not continuous with each other.
So, the proteins that are synthesized in the endoplasmic reticulum must be translocated to the destinations.
The synthesized proteins are transported through the network to golgy body in membrane-bound vesicles.
