BIOL1006 Lecture Notes - Lecture 23: Cell Membrane
Document Summary
Before reaching their final destination, the lipids or proteins within the transport vesicles still need to be sorted, packaged, and tagged so that they wind up in the right place. Tagging, packaging, and distribution of lipids and proteins takes place in the golgi apparatus, a series of flattened membranes. The golgi apparatus sorts and packages cellular products. The golgi apparatus in this white blood cell is visible as a stack of semicircular, flattened rings in the lower portion of the image. Several vesicles can be seen near the golgi apparatus. The receiving side of the golgi apparatus is called the cis face. The transport vesicles that formed from the er travel to the cis face, fuse with it, and empty their contents into the lumen of the golgi apparatus. As the proteins and lipids travel through the golgi, they undergo further modifications that allow them to be sorted.
