What membrane sacs that receive and package proteins?
What are the stacks of membrane covered sacs that package and transport protein to the outside of the cell called?
The Golgi is sometimes called the shipping and receiving department of the cell. They function to modify and package proteins and lipids into vesicles, small, spherically shaped sacs that bud from the ends of a Golgi apparatus. Vesicles often migrate to and merge with the plasma membrane, releasing their contents outside of the cell. It doesn't actually build compound but can modify them.
