A major function is the modifying, sorting and packaging of proteins for secretion. It is also involved in the transport of lipids around the cell, and the creation of lysosomes. The sacs or folds of the Golgi apparatus are called cisternae.
Cells synthesize a large number of proteins and lipids. The Golgi apparatus is integral in modifying, sorting, and packaging these macromolecules for cell secretion. The Golgi plays an important role in the synthesis of proteoglycans. It is also a major site of carbohydrate synthesis.Sep 19, 2014
