For example, plasma cells produce antibodies, which circulate in the bloodstream, bmw e46 bentley manual pancreatic acinar cells synthesize digestive enzymes, which are transported to the intestine via a series of progressively larger ducts (Figure tascam dp 32 tutorial
). In both types of cells, a large part of the cytosol is filled with rough ER. The synthesis and release of secretory proteins in acinar cells of the rat pancreas. These vesicles, which bud off from regions of the rough ER not coated with ribosomes, carry the proteins to the luminal cavity of another membrane-limited organelle, the Golgi complex. Three-dimensional reconstructions from serial sections of a Golgi complex reveal a series bmmw flattened membrane vesicles or bentlwy, surrounded by a number of more or less spherical membrane vesicles (Figure 5-49 ). Transfer vesicles from the rough ER fuse majual the cis. Region of the Golgi complex, where they deposit their proteins.
