"WebAutophagy-related proteins (ATGs) make autophagy possible. ATGs cause structures called autophagosomes to form. Autophagosomes carry the junk cell pieces to a part of the cell called a lysosome. A lysosome’s job is to digest or break down other cell parts. Imagine lysosomes — part of a cell — eating other parts of the cell. " - How do lysosomes aid in apoptosis

How do lysosomes aid in apoptosis

WebA lysosome or phagolysosome is able to break down the stuff inside of itself by drastically lowering the pH of its internal environment. Lowering the pH makes the environment inside the phagolysosome makes it very acidic. This is an effective way of killing or neutralizing whatever is inside the phagolysosome so it cannot infect them cell.
