Detailed explanation-1: -The three major groups of proteins that are synthesized by RER-bound ribosomes include secretory proteins, integral membrane proteins destined for ER-derived membranes, and the lumenal-resident proteins of the ER, Golgi, nuclear envelope, and lysosome.
Detailed explanation-2: -Answer and Explanation: The portion of the ER studded with ribosome is the outer surface of the rough endoplasmic reticulum. Therefore, they are also called the granular endoplasmic reticulum.
Detailed explanation-3: -Ribosomes on the rough endoplasmic reticulum are called ‘membrane bound’ and are responsible for the assembly of many proteins.
Detailed explanation-4: -The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins. Sometimes, when those proteins are made improperly, the proteins stay within the endoplasmic reticulum.
