What are ribosomes that are suspended in the cytosol known as?

Ribosomes that are suspended in the cytosol are referred to as free ribosomes. These ribosomes synthesize proteins that generally function within the cytosol itself, such as enzymes that catalyze biochemical reactions. They are distinct from bound ribosomes, which are attached to the endoplasmic reticulum and are primarily involved in synthesizing proteins destined for export, membrane insertion, or lysosomes.

Free ribosomes play a crucial role in cellular metabolism by producing proteins necessary for various intracellular activities. This distinction between free and bound ribosomes highlights the different pathways that proteins can take based on their intended destination within the cell. Understanding these details is important for comprehending cellular function and the protein synthesis process as a whole.
