The Golgi Apparatus modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside the cell.
The Golgi apparatus is a central intracellular membrane organelle for trafficking and modification of proteins and lipids. Its basic structure is a stack of tightly aligned flat cisternae. In mammalian cells, dozens of stacks are concentrated in the pericentriolar region and laterally connected to form a ribbon.
The job of the Golgi apparatus is to process and bundle macromolecules like proteins and lipids as they are synthesized within the cell.
(1) The main function of golgi body is secretion, so it is large sized among the secretory cells. (2) Glycosidation of lipids i.e., addition of oligosaccharides to produce glycolipids. (3) Glycosylation of proteins i.e., addition of carbohydrate to produce glycoproteins. (4) Formation of primary lysosomes.
Golgi apparatus. Golgi apparatus. The stacks of flattened membranous vesicles are called Golgi apparatus. It basically stores, packs and modifies the products in vesicles. It temporarily stores protein that moves out of the cell through the vesicles of the Golgi apparatus.
