The lysosome is one of the most important organelles in the cell and it is a membrane-bound organelle. They are well-known as terminal catabolic stations, also known as ‘suicide bags’ that eliminate waste from cells and scavenge metabolic raw materials to maintain vital biosynthetic processes under famine. The lysosome can convey the overall metabolic state of the cell to nutrient-sensing modules as well as influence the pace of metabolic events taking place in other parts of the cell. The organelle is acidic, containing digestive hydrolytic enzymes which are capable of breaking down large molecules. The lysosomes also serve as a defense mechanism against infection, and a bacterium will frequently be engulfed by a cell and placed in a lysosome for elimination.
