Define Ribosomes

Ribosomes are small, but complex structures, approximately 20 to 30 nm in diameter, containing two unequally sized subunits, referred to as large and small subunits which fit closely together as seen in Figure. These are the small cellular components composed of specialized ribosomal RNA and protein. We have just read that they are found studded like jewels on RERs. They are responsible for synthesizing proteins that form the membrane of secretory organelles and lysosome membranes.
