And once they are produced, they travel through the smooth endoplasmic material and eventually end up in the Golgi apparatus. And the Golgi apparatus basically modifies those hydrolytic enzymes and then releases them inside secretory vesicles, which then fuse with endosomes, such as, for example, phangosomes. And that creates our Lysosome. So basically, Lysosomes can also be used inside cells to destroy things like bacteria. So inside our immune system, we have cell known as phagocytes. And those phagocytes undergo a process known as phagocytosis.
