Lysosomes


Lysosomes are small membranous sacs that contains digestive (hydrolytic) enzymes.

Lysosomes release digestive enzymes to:

break down worn-out cell parts (a process called autophagy)
break down bacteria and other foreign objects that have been engulfed by the cell
As a result of these functions, lysosomes are sometimes called the “cellular garbage disposals.”
