What are Ribosomes?

Ribosome The Virtual Cell

Ribosomes are the protein assemblers of a eukaryotic cell. They are typically composed of two subunits: a large subunit and a small subunit. These two units join together to produce proteins in a process called translation.

Ribosomes may be suspended in the cytosol of the cell or bound to the endoplasmic reticulum. Free ribosomes usually make proteins that will function in the cytosol, while bound ribosomes usually make proteins that are exported outside of the cell or included in the cell's membranes.
