The Golgi apparatus (also referred to as Golgi bodies)
modifies, sorts, and ships
proteins. It also plays a role in the synthesis of lipids for
secretion or for internal use. In the Golgi apparatus, proteins and
lipids undergo final processing, sorting, and packaging. The
membranes of the Golgi apparatus are arranged in stacks of
flattened sacs whose edges break away as vesicles.
