Document Summary
Has ribosomes that bind to it when protein synthesis begins, so they are found in higher magnitudes in cells that need more protein secretion or cells that need extensive membrane synthesis. Packages and discharges the proteins that were synthesized in the rough er. The part responsible for transporting will bud off of the rest of the er and become a transport vesicle (this part of the er is replaced with a newly synthesized portion created in the rough er) Also works as a detoxifier in the liver cells of harmful substances that come from outside the body. Each complex consists of cisternae flattened, membrane enclosed sacs. Once the transport vesicles from smooth er are bundled, they enter the golgi stack; the sacs fuse with the membrane and the contents are released into the stack. Raw materials become finished products here (raw protein becomes something that can be used) Finished products are transported to their destinations.
