Detailed explanation-1: -The Golgi apparatus is the central organelle mediating protein and lipid transport within the eukaryotic cell.
Detailed explanation-2: -From the endoplasmic reticulum, proteins are transported in vesicles to the Golgi apparatus, where they are further processed and sorted for transport to lysosomes, the plasma membrane, or secretion from the cell.
Detailed explanation-3: -The organelle that transports proteins is called the endoplasmic reticulum, or ER. The ER is an organelle made up of sac-like membranes that are folded many times. Proteins are synthesized by ribosomes that are attached to the ER.
Detailed explanation-4: -COPII-coated vesicles transport cargo proteins from the ER to the Golgi; COPI-coated vesicles transport cargo in the retrograde direction (from the cis-Golgi back to the ER) and between Golgi cisternae; and clathrin-coated vesicles form from the plasma membrane and the TGN to fuse with endosomes or lysosomes (Fig.
