Final answer:
Newly translated proteins enter the Golgi apparatus through the cis face and exit through the trans face.
Step-by-step explanation:
The newly translated proteins enter the Golgi apparatus through the cis face. This is the receiving side of the Golgi. As the proteins and lipids travel through the Golgi, they undergo further modifications and are sorted. The modified and tagged proteins are then packaged into secretory vesicles that bud from the trans face of the Golgi. These vesicles can either deposit their contents into other parts of the cell for internal use or fuse with the plasma membrane and release their contents outside the cell.
