Describe the pathway that newly synthesized polypeptides take on route for secretion
What will be an ideal response?
The rough ER synthesizes proteins, which then make their way into the smooth ER. The smooth ER packages the proteins within transport vesicles that pass to the Golgi complex. The contents of the vesicle enter the Golgi complex where they may be modified. Eventually, the secretory products are packaged into secretory vesicles, which bud off the Golgi complex and make their way to the plasma membrane along components of the cytoskeleton. On appropriate stimulation, the secretory vesicles fuse with the plasma membrane and empty their contents into the ECF via exocytosis.
