Golgi apparatus

Golgi Apparatus

The Golgi apparatus, also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. It was identified in 1897 by the Italian scientist Camillo Golgi, and named after him.

Structure

The Golgi apparatus is 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 Golgi apparatus function can result in diseases, including Alzheimer's disease, Parkinson's disease, and other neurodegenerative disorders.
