Here's why:
* Lysosomes are the "recycling centers" of the cell: They contain powerful enzymes that break down various substances, including worn-out cell parts, debris, and yes, even invading microbes.
* Phagocytosis: Some cells, like white blood cells, engulf microbes through a process called phagocytosis. The microbe is enclosed in a vesicle that then fuses with a lysosome. The lysosomal enzymes then break down the microbe.
While lysosomes are the primary players in cellular digestion, other structures can also be involved:
* Phagosomes: These are the vesicles that initially enclose the microbes.
* Proteasomes: These are protein complexes that break down proteins, which can be helpful in degrading microbial proteins.
So, while lysosomes are the main "digestive powerhouses," other structures collaborate to dismantle and neutralize microbes within the cell.
