The Golgi apparatus is present in most eukaryotic cells, but tends to be more prominent where there are a lot of substances, such as enzymes, being secreted.
The transport mechanism itself is not yet clear; it could happen by cisternae progression (the movement of the apparatus itself, building new cisternae at the cis face and destroying them at the trans face) or by vesicular transport (small vesicles transport the proteins from one cisterna to the next, while the cisternae remain unchanged).
An example of the Golgi complex's functioning is the modification of glycoproteins (used in cell membranes).
It is involved in intracellular transport and modification of secretory proteins, membrane proteins, and proteins that remain membrane-bounded within the cell, in distinction to proteins such as hemoglobin and keratin that lie free in the cytoplasm.
Biochemically, the Golgi apparatus is a transition cell component that functions as intermediaries between the endoplasmic reticulum and the cell surface.
The Golgi apparatus of both cell types is engaged in the segregation, modification, and secretion of lipoproteins to the circulation (to the capillary space for liver and to the lymphatics for intestine).
