And three, our vacuum basically creates an acidic environment that allows hydrolytic enzymes to break down macromolecules as well as waste products. So generally in plants, vacuums function to store harmful materials and waste products, store water and maintain hydrostatic pressure, also known as turkey pressure. And our acidic environment inside plant cells is basically a result of the integral proteins that are found inside the phospholipid layer of our plant vacuums. Basically, those proteins inside the phospholipid bilayer pump H ions into our vacuole and that increases the acidity and lowers our PH. And that gives these enzymes, the hydrolytic enzymes, the ability to break down the waste products stored inside vacuoles. Now, in animal cells, vacuoles are much smaller, they do not store as much water, and they basically function in aiding endocytotic and endo and exocytotic processes.
