Document Summary
Microbiology of the cell (6th uoft custom edition) Exocytosis: secretory pathway to deliver cargo to plasma membrane (pm) or extracellular (ec) space. Endocytosis: remove pm and deliver to internal components: endosomes: captures important nutrients in the ec space. Lumen is the interior space of each membrane-enclosed compartment. Transport vesicles used to move cargo around. The molecular mechanisms of membrane transport and maintenance of compartmental diversity. Molecular markers on cytosolic surface of membrane are guiding cues for incoming traffic: ensures transport vesicles fuse only with correct compartment, many are found on more than one compartment combination marks specificity. Before fusing with target membrane, discard the coat to allow direct fusion. Three well-characterized types of coated vesicles: clathrin-coated: mediate transport from golgi and from pm, copi-coated, copii-coated: mediate transport from er and golgi cisternae. Transports material from plasma membrane and bw endosomal and golgi compartments.
