The Golgi apparatus is an organelle located near the nucleus. It consists of a stack of membrane bound sacs called cisternae. It is known as the sorting centre for proteins destined for secretion which arrive from the endoplasmic reticulum. Inside the Golgi proteins undergo further post-translational modification such as trimming of core oligosaccharides, addition of sugars and removal of sugars. proteins leaving the Golgi are directed to the appropriate destination, which may be the cell surface, a lysosome or a secretory vesicle. The structure of the Golgi consists of a cis face which the proteins enter and a trans face where the proteins leave.
