Lysosomes have several key functions: they release enzymes to destroy worn out organelles, digest material brought into cells through phagocytosis such as bacteria engulfed by white blood cells, and release enzymes outside of cells to digest other cells through exocytosis. They can also cause autolysis and self-destruction of cells by breaking down and releasing their enzymes.
