Why Are Lysosomal Enzymes Harmful to a Cell?

Lysosomes are membrane-bound organelles with roles in processes involved in degrading and recycling cellular waste, cellular signalling and energy metabolism. Defects in genes encoding lysosomal proteins cause lysosomal storage disorders

lysosomal storage disorders
Lysosomal storage diseases (LSDs) are heritable (inborn) errors of metabolism that affect the function of the lysosome. LSDs comprise a group of 70 monogenic disorders of lysosomal catabolism, most of which are inherited as autosomal recessive traits, but three are X-linked.
, in which enzyme replacement therapy has proved successful.

Why do lysosomes digest damaged cells?

A lysosome is a membrane-bound cell organelle that contains digestive enzymes. ... They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.

Why don t lysosomal enzymes destroy cells?

The lysosomal enzyme does not destroy its own cytoplasm, because of the following reasons. The enzymes are separated from the cytoplasm by the lysosomal membrane. The enzymes have the capability of recognising and digest only foreign matter.
