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.
