Bound and free ribosomes
WebJul 7, 2024 · There are two types of ribosomes, free and fixed (also known as membrane bound). They are identical in structure but differ in locations within the cell. Free ribosomes are located in the cytosol and are able to move throughout the cell, whereas fixed ribosomes are attached to the rER. Why do ribosomes have two subunits? WebApr 11, 2024 · Both free and ER-bound ribosomes synthesize proteins.
