Final answer:
The Golgi apparatus is an organelle involved in processing proteins and lipids. It is associated with diseases such as congenital disorders of glycosylation, which affect the processing of glycoproteins.
Step-by-step explanation:
The Golgi apparatus, also known as the Golgi body, is an organelle involved in processing proteins and lipids. It modifies, sorts, and packages substances for secretion out of the cell or for use within the cell. Many diseases are associated with the Golgi apparatus, such as congenital disorders of glycosylation, which affect the processing of glycoproteins. For example, defects in the Golgi apparatus can lead to abnormal sugar molecules being added to glycoproteins, resulting in various health conditions.
