Lysosomes are membranous organelles that contain digestive enzymes. lysosomes can function inside the cell, where their enzymes digest particles taken in by endocytosis or worn‑out cell components. lysosomes can also release their enzymes outside the cell, where the enzymes break down extracellular material. i‑cell disease is a lysosomal storage disease that results in the buildup of carbohydrates, lipids, and proteins as inclusion bodies within the cell. which is the probable cause? the cell does not take up food molecules by endocytosis. the golgi apparatus cannot target the appropriate enzymes to the lysosome. lysosomes accumulate extra lipid‑digesting enzymes. the lysosome cannot fuse to the cell membrane to release enzymes extracellularly.
