Now let's move on to our Lysosomes, which are described by these two green vesicles here. So Lysosomes are essentially specialized vesicles that contain hydrolytic enzymes. So that means inside the environment of our Lysosome, we have a relatively low PH, it's about five. And these Lysosomes basically help break down unwanting material inside the cell. Now let's move on to another type of specialized vesicle known as the paroxysome. The paroxysome are also known as microbodies.
