Q
What are lysosomes for
A
Lysosomes are specialised forms of vesicles that contain hydrolytic enzymes. They are responsible for breaking down waste material in cells, including old organelles. They play an important role in the immune system as they are responsible for breaking down pathogens ingested by phagocytic cells. They also play an important role in programmed cell death or apoptosis.
