The Lysosome (Suicidal bag of the Cell)

Lysosomes are single membrane bound structures found in animal cells. These were discovered by  D’Duve (Nobel prize-1974). 
 It is formed by golgi bodies or endoplasmic reticulum. Lysosome contains many digestive enzymes like “proteases,lipases,carbohydratases ,etc”. These become active at the acidic pH.  Many types of lysosomes are found as “Primary lysosomes,secondary lysosomes,residual bodies ,autophagic vacuoles”.

Lysosome is considered as “ Suicidal bag of cell”  because its enzyme can digest all the parts of cell when lysosome bursts.

  Function
·    Primary lysosome  helps in digestion of material taken by cell through endocytosis.
·       Lysosomes help in autolysis of injured cells.
·       Lysosomal enzymes facilitates intracellular digestion.

·       Lysosomal enzymes digest food inside protozoans.
