Lysosomes are organelles found in the cytoplasm of a cell. Lysosomes work like the digestive system to break down, or digest, proteins, acids, carbohydrates, dead organelles, and other unwanted materials.[1]

Lysosomes work by breaking up larger molecules into smaller molecules. Those smaller molecules can then be used again as building blocks for other large molecules.[1]
