One type of programmed cell death occurs when these bodies process old organelles and proteins and is called autophagy.
Metachromatic leukodystrophy is caused by a problem in one enzyme of this organelle. One genetic disorder in trafficking proteins here is I-cell disease. That trafficking uses the mannose-6-phosphate modification. Pompe's disease and Tay-Sachs disease result when one of its proteins are missing. In order for its enzymes to function, it has a pH that is much more acidic than its surroundings.  One type of programmed cell death occurs when these bodies process old organelles and proteins and is called autophagy. It will often fuse with a vacuole to digest the contents of it. For 10 points, name this organelle which helps the cell to break up debris and food obtained from phagocytosis.
