Answer/Explanation:
The lysosome is a membrane-bound organelle in eukaryotic cells that is important for breakdown of old cellular materials, large molecules and even bacteria and viruses. The lysosome contains lysosomal enzymes, which are digestive enzymes that catalyse the breaking down of such substances. Lysosomes are very acidic to aid the function of these enzymes.
With a defective lysosomal enzyme, you might expect the cell to have a build up of damaged or old organelles, and also a build up of macromolecules that the cell needs to lysosomes to break down. This could mean that the cell becomes starved of a food source and unable to perform respiration and other related tasks.
