Lysosomes are formed by budding off vesicles from the Golgi apparatus. They are bounded by a single membrane about 500 nm and are involved in intracellular digestion, containing the enzymes needed to digest all types of macromolecules. The enzymes present in such vesicles belong to acid hydrolases: The acidic condition is maintained by pumping protons into the interior of the lysosomes from the cytoplasm. (Lysosomes contain hydrolytic enzymes that require acidic pH to function, for the functioning of these enzymes pH is decreased by actively pumping H+ to the cytoplasm).
