WebMar 15, 2024 · Lysosomes are round membrane-bound organelles with a single outer lysosomal membrane. The membrane is impervious to the acidic contents of the lysosome. This protects the rest of the cell from the … WebIn several disorders, including Alzheimer's disease (AD), defective lysosomal acidification contributes to this proteolytic failure. The complex regulation of lysosomal pH makes this process vulnerable to disruption by many factors, and reliable lysosomal pH measurements have become increasingly important in investigations of disease mechanisms.
