There are three main types of coat protein associated with transport vesicles. What is the general purpose of these coat proteins? and where would each of the three types be found in the exocytotic and endocytic pathways of the cell

Describe the mechanisms by which a transport vesicle is able to find and fuse with its target membrane. Be sure to include all relevent proteins and processes involved in the recognition, docking and fusion of membranes

Glycosylation performs many important functions in the cell, from ensuring the proper folding of proteins to cell-cell recognition. What are M6P groups, where are they added, and what is their purpose in exo/endocytotic cycling? How is their proper function reliant on organellar pH?
