Final answer:
In translation, proteins destined for the ER and Golgi are synthesized on ribosomes in the rough ER lumen. They are then modified in the Golgi and sorted before being sent to their final destination.
Step-by-step explanation:
In the process of translation, proteins destined for the endoplasmic reticulum (ER) and Golgi apparatus are synthesized on bound ribosomes in the rough ER lumen. They then travel to the Golgi apparatus by vesicles. In the Golgi, these proteins are modified and sorted before being sent to their final destination.
After the proteins are synthesized in the rough ER, they undergo structural modifications in the Golgi apparatus. The Golgi apparatus further modifies the proteins by adding carbohydrates to them. Once the proteins are fully synthesized and modified, they are packaged into secretory vesicles that bud from the trans face of the Golgi. Some secretory vesicles deposit their contents into other parts of the cell, while others fuse with the plasma membrane and release their contents outside the cell.
