The lysosomal membrane acts as a protective shield between the powerful

digestive enzymes within the lysosome and the cytoplasm, preventing their
ggq ggq ggq ggq ggq ggq ggq ggq ggq ggq
leakage into the cytoplasmic matrix. Disruption of the membrane by various
ggq ggq ggq ggq ggq ggq ggq ggq ggq ggq ggq
treatments or cellular injury leads to a release of the lysosomal enzymes,
ggq ggq ggq ggq ggq ggq ggq ggq ggq ggq ggq ggq
which can then react with their specific substrates, causing cellular self-
