Bound ribosomes
WebWhen a ribosome begins to synthesise proteins that are required by specific organelles, the ribosome responsible for the production of the protein may become “membrane-bound.” Specifically, this occurs in eukaryotic cells in a portion of the endoplasmic reticulum (ER) referred to as the “rough ER.” WebRibosomes can be free in the cytosol or bound to a membrane have the same structure and can interchange their location. Proteins produced by free ribosomes are usually …
