Caption:Often associated with the endoplasmic reticulum, the Golgi apparatus is responsible for the modification and sorting of some biomolecules. The proteins inserted into the lumen of the ER are transported to the Golgi apparatus for sorting and secretion. Vesicles carry modified material to destinations inside and outside of the cell.
Notes:The lumen is the interior of the Golgi sacs. Vesicles bud off from the ends of the sacs.
