WebRibosomes can function in a “free” form in the cytoplasm, called free ribosomes. However, they can also “settle” on the endoplasmic reticulum (ER) to form “rough endoplasmic reticulum (RER).” Ribosomes in close association with the endoplasmic reticulum can facilitate the further processing of newly made proteins.
