... basic way for a cell to feed (except for photosynthesis in plants, which don't have lysosomes). The membrane of the lysosome is impermeable for lysozyme
, the enzyme that does the actual digestion, to protect the cell interior from being digested by its own enzyme. Lysosomes are made in the Golgi ...
... On the other hand, bacteriophages must break open, or lyse , the cell to exit. To do this, the phages have a gene that codes for an enzyme called lysozyme
. This enzyme breaks down the cell wall, causing the cell to swell and burst. The new viruses are released into the environment, killing the host ...
