A lysosome is a type of membrane-bound organelle that is present in animal cells. Ranging in diameter from approx. 50nm to 1 Î¼mÂ§, lysosomes have a single outer membrane consisting of a phospholipid bilayer and contain acid hydrolases which are enzymes capable of breaking-down macromolecules.
Lysosomes are cellular organelles that contain acid hydrolase enzymes that break down waste materials and cellular debris. They can be described as the stomach of the cell. Lysosomes digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria.t pH 4.8, the interior of the lysosomes is acidic compared to the slightly basic cytosol (pH 7.2). The lysosome maintains this pH differential by pumping in protons (H + ions) from the cytosol across the membrane via proton pumps and chloride ion channels.
