Quizplus · Accepted Answer

RER and SER have different protein make-up. RER is studded with ribosomes which synthesize proteins, while SER lacks ribosomes and is involved in lipid metabolism. Therefore, the presence or absence of ribosomes and the protein make-up of the ER can be used to distinguish RER from SER.
