two organelles pulse-chase experiments indicate the it takes 10 to minutes (fig 7-7) for newly synthesized pancreatic enzymes to reach the golgi complex from their site of synthesis in the RER. In some cell the vesicles that move from the ER to the golgi complex are coated with a bristly layer of applied protein the function of these "coated" vesicles it discussed on page 283. In some cell ther is evidence of direct continute between the cavities of the ER and those of the golgi complex. These are most evident in high-volt age electron micrographs. Where thicker section can be examined
