The Dynamic Nature of the Endomembrane System ❖Most organelles are part of a dynamic system in which vesicles move between compartments. ❖Biosynthetic parthways move proteins, carbohydrates and lipids within the cell. ❖Secretory pathways discharge proteins from cells. ❖Endocytic parthways move materials into cells. ❖Sorting signals are recognized by receptors and target proteins to specific sites
