[The lysosome is a membrane bound structure that contains hydrolytic enzymes for digesting macromolecules.]
The lysosome is a membranous bag which contains hydrolytic enzymes that are
used to digest macromolecules. The lysosome contains over 40 enzymes, some of
which are the proteases, nucleases, and phopholipases. These enzymes optimally
work at a pH of 5 (acidic), so should these enzymes leak out they would cause
minimal damage to the cytoplasm. These enzymes, called hydrolases, are made in
the ER and transported to the lysosome by the
Golgi complex, using a vesicle.
Should certain hydrolases be missing from the cells, serious illness can
occur because of a buildup of molecules which cannot be digested by the lysosome.
These extra molecules can interfere with normal cell functions, causing
