WebAutophagic function of lysosomes also helps indirectly in a process called apoptosis. Apoptosis - or programmed cell death - is when a cell becomes 'old', or gets infected by certain kinds of pathogens and receives the signal for self-destruction. The contents of the lysosome then 'spill' out into the cell and eat up the cell from the inside. WebApoptosis, or programmed cell death, is a physiologically and morphologically distinct way of eliminating cells. Apoptosis occurs without induction of the inflammatory response …
