For 10 points, name this organelle that comes in rough and smooth forms and provides a transport network throughout the cell.
In addition to causing the retrieval of v-SNARE proteins, the coat protein COP I targets proteins for this organelle, while COP II targets proteins exiting this organelle. The common sequence KDEL marks proteins for retention in this organelle, and most proteins synthesized in one type of this organelle undergo glycosylation. Ribosomes are present on the surface of one type of this organelle. For 10 points, name this organelle that comes in rough and smooth forms and provides a transport network throughout the cell.
