Golgi Apparatus

Golgi Apparatus is an organelle found in most eukaryotic cells. It was identified in 1897 by the Italian scientist Camillo Golgi, and is sometimes referred to as the 'Golgi body', 'Golgi complex', or simply 'the Golgi'.

Structure

The Golgi apparatus is composed of a series of flattened, stacked pouches called cisternae, and is located in the cytoplasm near the cell nucleus. The number of 'Golgi bodies' in a cell varies according to its function.

Function

The primary function of the Golgi apparatus is to process and package the macromolecules such as proteins and lipids that are synthesized by the cell. It is particularly important in the processing of proteins for secretion. The Golgi apparatus forms a part of the endomembrane system of eukaryotic cells.

Role in Disease

Defects in the function of the Golgi apparatus can lead to diseases such as congenital disorders of glycosylation, which involve defects in the glycosylation of proteins.
