Document Summary
Cell is compartment and has compartments within need to regulate composition of each compartment. movement of proteins within cell to different compartments : out of cell , into cell , exocytosis and endocytosis. In the diagram names of compartments you should know er, peroxisomes, endosomes, lysosomes, mitochondria, nucleus. Should know how proteins get into each compartment what signal lets it in, and what. All proteins being life in the cytosol translation of all proteins start in the cytosol except for the odd ones in the mitochondria and chloroplasts. Transmembrane transport embedded in membrane each protein called translocators. Vesicular transport both directions okay vesicles can move. ***only one way into green area through er only way into this vesicle transport system. once in er protein can make way to golgi. Free diffusion of small molecules (<5000 daltons) : anything bigger needs to be carried through, and requiring a nuclear localization signal.
