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: -The RER is termed “rough” due ribosomal attachments to the surface compared to the SER, which does not have ribosomes.
Detailed explanation-3: -The rough endoplasmic reticulum (RER) is so named for the appearance of its outer surface, which is studded with protein-synthesizing particles known as ribosomes.
