Well, a Lysosome is a spherically shaped, membrane enclosed organelle that are found in animal cells, although recent evidence shows that they can also be found in plant cells. So basically, Lysosomes, just like vacuums, contain an acidic environment that is created as a result of the integral proteins found inside the phospholipid bilayer of the Lysosomes. So the H ions are pumped from the cytosol into the Lysosome and that creates that low PH, about 4.8 to five PH. Now, this low PH allows our hydrolytic enzymes, also known as acid hydrolase enzymes, to basically break down the four different types of macromolecules. And this includes lipids proteins, nucleic acids, as well as carbohydrates. So all these different types of macromolecules, as well as other type of waste products and materials are broken down inside our Lysosomes as a result of these different types of enzymes.
