WebbRibosomes are the cellular structures responsible for protein synthesis. The word “synthesis” means “to combine things to produce something else.” In this context, protein synthesis means combining different amino acids together to form a protein. Ribosomes join amino acids together in a chain to form a protein ( Figure 1 ). WebbRibosomes are available in two different types: free and fixed (also known as membrane bound). They have the same structure but differ in their locations within the cell. Free ribosomes can be found in the cytosol and move throughout the cell, whereas fixed ribosomes can be found in the rER.
