How are proteins transported out of the endoplasmic reticulum to the Golgi apparatus?

Best Answers

Correctly folded and assembled proteins in the ER are packaged into COPII-coated transport vesicles that pinch off from the ER membrane. ... The Golgi apparatus distributes the many proteins and lipids that it receives from the ER and then modifies the plasma membrane, lysosomes, and secretory vesicles. read more

a. the retrieval of ER resident proteins from the cis-Golgi or the ER-Golgi intermediate compartment. b. the uptake of extracellular molecules by endocytosis and the transport of molecules from the trans Golgi network to the lysosomes. read more

Endoplasmic reticulum and Golgi apparatus are two membrane-bound organelles found in eukaryotes. Both these organelles are closely associated and functionally related. Both endoplasmic reticulum (ER) and Golgi apparatus are two components of the endomembrane system of a cell. Lysosomes and vesicles are the other components of the endomembrane system. read more

The endoplasmic reticulum serves many general functions, including the folding of protein molecules in sacs called cisternae and the transport of synthesized proteins in vesicles to the Golgi apparatus. read more
