Document Summary

Dynamic, coordinated network of all cell(cid:495)s organelles and related structures. ** all of these organelles are membrane bound. Large amounts of material trafficked btw each organelle/structure. All endomembrane organelles are structurally and functionally distinct from each other. Step (cid:883) = (cid:494)cargo(cid:495) containing vesicle buds off the donor membrane compartment. Step 2 = nascent vesicle is transported through cytosol to recipient membrane compartment (cid:858) (cid:859) Step 4 = entire process of budding and fusion is repeated and can occur in reverse direction. Of any proteins that (cid:494)escaped(cid:495) to recipient compartment back to donor membrane compartment. Biosynthetic pathway, secretory pathways (2 types), endocytic pathway all rely on transport vesicles. *protein synthesis takes place in cytoplasm (cid:523)ribosomes make the proteins (cid:524) All ribosomes used to make them are bound to er (all endome proteins made here) Er to golgi, to endosomes and then either lysosomes (vacuoles in plants/fungi/yeast) or some times plasma membrane. Running all the time, not regulated or induced.
