Introduction The Golgi apparatus, also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. It is Part of the endomembrane system in the cytoplasm Golgi apparatus packages proteins into membraneboundvesicles inside the cell before the vesicles are sent to their destination.

Introduction resides at the intersection of the secretory, lysosomal, and endocytic pathways. It is of particular importance in processing proteins for secretion, containing a set of glycosylation enzymes that attach various sugar monomers to proteins as the proteins move through the apparatus.

Golgi apparatus Discovery The Golgi apparatus was descovered in 1897 by Italian cytologist Camillo Golgi. In Golgi’s early studies of nervous tissue, he had established a staining technique that he referred to as reazione nera, meaning “black reaction”; today it is known as the Golgi stain.

Golgi apparatus structure The golgi body comprised of a series of five to eight cup-shaped, membrane-covered sacs called cisternae that look something like a stack of deflated balloons. In some unicellular flagellates, however, as many as 60 cisternae may combine to make up the Golgi apparatus.

Subcellular localization The subcellular localization of the Golgi apparatus varies among eukaryotes : 1. In mammals, a single Golgi apparatus is usually located near the cell nucleus, close to the centrosome. Tubular connections are responsible for linking the stacks together. 2. In yeast, multiple Golgi apparatuses are scattered throughout the cytoplasm (as observed in Saccharomyces cerevisiae). 3. In plants, Golgi stacks are not concentrated at the centrosomal region and do not form Golgi ribbons.

Golgi apparatus Function • transports lipids to vital parts of the cell and creates lysosome • As part of eukaryotic cells, the Golgi apparatus works in unison with the endomembrane system. • production of glycosaminoglycan's, which go on to form parts of connective tissues. • The Golgi will use a xylose link to polymerize the glycosaminoglycan's onto proteins to form proteoglycan

Vesicular transport The vesicles that leave the rough endoplasmic reticulum are transported to the cis face of the Golgi apparatus , where they fuse with the Golgi membrane and empty their contents into the lumen. Once inside the lumen, the molecules are modified, then sorted for transport to their next destinations. The Golgi apparatus tends to be larger and more numerous in cells that synthesize and secrete large amount of substance.
