The Golgi complex is made several flattened membranes sacs, but can be ultimately divided into two sections: the Cis golgi and the Trans Golgi Network (TGN). The Cis golgi functions as the receiving end for newly synthesized proteins from the lumen of the Endoplasmic Reticulum (ER). Vesicles containing proteins from the ER merge with the Cis golgi allowing the proteins to enter the Golgi complex. As the Cis golgi received proteins from the ER, the proteins then begin their modification moving along membrane to membrane towards the TGN. At the other end of the golgi complex, the newly modified protein arrives at the TGB where it is then send off to different parts of the cell via a transport vesicle.
hope i helped u:)
