Answer:
The answer is C
Explanation:
Proteins that were sinthesized in the endoplasmic reticulum are able to leave this organelle inside vesicles that are formed through evagination of the reticulum membrane. These vesicles can merge with the golgi membrane, spreading its contents inside the golgi apparatus. This process can be repeated through all of Golgi's cisternaes, and when the last cisternae is reached, these vesicles can be directed towards the plasma membrane. Once the vesicles and the plasma membrane are merged, all the molecules that were contained inside the vesicle are exported from the cell into the extracellular space.
