Question

During a bacterial infection, macrophages will seek out and engulf the invading bacteria into vesicles via phagocytosis. The bacteria will then be degraded inside the macrophage. Which organelle do you think participates directly in this degradation process

Answer 1

After the microorganism is ingested by the white blood cell a vesicle that contains the pathogen is formed. This vesicle fuses with an organelle that contains up to 40 hydrolytic enzymes. That organel is called a lysosome
