插图：B. The Endoplasmic Reticulum and Golgi ApparatusA network of membrane sheets and tubules called the endoplasmic reticulum (ER) extends from the outer membrane of the nucleus. The aqueous region enclosed within the endoplasmic reticulum is called the lumen. In many cells, part of the surface of the endoplasmic reficulum is coated with ribosomes that are actively synthesizing proteins. As synthesis continues, the protein is translocated through the membrane into the lumen. In the case of membrane-spanning proteins, part of the protein remains embedded in the membrane after it is released from the ribosome. Proteins destined for export from the cell are completely extruded through the membrane into the lumen, where they are packaged in membranous vesicles. These vesicles travel through the cell and fuse with the plasma membrane, releasing their contents into the extracellular space. The synthesis of proteins destined to remain in the cytosol occurs at ribosomes that are not bound to the endoplasmic reficulum. Many enzyme systems involved in the metabolism of lipids are concentrated in regions of the endoplasmic reticulum that have no attached ribosomes.In many species, a complex of flattened, fluid-filled, membranous sacs called the Golgi apparatus is often found close to the endoplasmic reticulum and the nucleus. Vesicles that bud off from the endoplasmic reticulum fuse with the Golgi apparatus. The contents of the vesicles may be chemically modified as they pass through the layers of the Golgi apparatus. The modified products are then sorted, packaged in new vesicles, and transported to specific destinations inside or outside the cell.
