Golgi complex

Golgi complex n GOLGI APPARATUS

* * *

a complex intracellular compartment of eukaryotes, occupying the perinuclear region and consisting of a number of stacked, flattened sacs (cisternae) with associated tubules and vesicles. Its primary function is to process substances synthesized in the endoplasmic reticulum; in addition it synthesizes some carbohydrates, such as hyaluronan and chondroitin sulfate. Transport vesicles from the endoplasmic reticulum fuse with the Golgi complex at the cis face, their cargo is processed while passing through the cisternae, and the processed products are transported from the trans face to the trans-Golgi network for sorting and packaging. The mechanism by which cargo moves through the Golgi complex is not clear; one model proposes transport between cisternae by vesicular budding and fusion, while another proposes dynamic remodeling and recycling so that the cisternae themselves change in composition and move in a cis-to-trans direction. Called also Golgi apparatus and Golgi body. See illustration and see Plate 12.
