Explanation:
Detailed explanation-1: -The ribosome that is synthesizing the protein is directly attached to the ER membrane. These membrane-bound ribosomes coat the surface of the ER, creating regions termed rough endoplasmic reticulum, or rough ER (Figure 12-36A).
Detailed explanation-2: -Plasma membrane and lysosomal proteins also travel from the rough ER to the Golgi and then to their final destinations. Still other proteins travel through the initial steps of the secretory pathway but are then retained and function within either the ER or the Golgi apparatus.
Detailed explanation-3: -Many proteins that are synthesized in the RER are packaged into vesicles and transported to the Golgi apparatus.
