Question

question 36
which organelle of a phagocyte ultimately destroys an invading pathogen?
phagosome
lysosome
nucleus
mitochondria

Explanation:

Lysosomes contain digestive enzymes. When a phagocyte engulfs a pathogen, the phagosome (which contains the pathogen) fuses with a lysosome. The enzymes in the lysosome then break down the pathogen. Phagosome is just the vesicle that holds the pathogen initially. Nucleus is for genetic information storage and regulation. Mitochondria are for energy production (ATP synthesis).

Answer:

Lysosome
