Educated Guess: the Golgi Apparatus?


If so:

The Golgi-apparatus is the dispatching centre of the cell: Proteins etc. destined for "export" to destinations outside the cell (e.g. hormones) are packaged here in vesicles that will be directed towards the cell membrane.

Apart from that, this is where Glysosylation takes place, the attachment of sugar residues to proteins.

An example: Transferrin. This protein contains two specific high-affinity Fe(III) binding sites. Once secreted into the bloodstream, Transferrin carries the iron atoms, mainly towards the bone marrow so they can be used in the manufacture of red blood cells. Before secretion, the Transferrin is glycosylated in the Golgi apparatus....
