Lysosome Lysosome are liquid-filled sack surrounded by a single membrane.
Lysosomes are the cell s disposable system of trash.
They digest the products taken in by the cell such as the bacteria taken in by endocytosis. Once bacteria comes in, it is enclosed in vacuoles that are formed from the plasma membrane. The enzymes become activated as the pH becomes more acidic. The bacteria inside the vacuole is broken down by the enzyme when the vacuole becomes secondary lysosome. Also, lysosome help the cell tear down parts of themselves and reuse the material.
