Sunderland MA . Sinauer Associates ; 2000. Search term Lysosomes Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers— proteins , nucleic acids, carbohydrates, and lipids. Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself. In their simplest form, lysosomes are visualized as dense spherical vacuoles, but they can display considerable variation in size and shape as a result of differences in the materials that have been taken up for digestion Figure 9. Lysosomes thus represent morphologically diverse organelles defined by the common function of degrading intracellular material.
Lysosomes are the main digestive compartment of the cell. As such, they contain a variety of enzymes capable of degrading different types of biological material including nucleic acids, lipids and proteins among others.
