Lysosomes were
discovered by Christian
de Duve in 1953 . They are
found in eukaryotic cells.
Lysosomes are knows
as suicidal bags.
Structure:
They
are spherical bodies
with single unit membrane. Inside this
unit membrane there is a
lipid layer. Inside the
lipid layer there are
Hydrolytic enzyme mixture.
That can digest
material within the cell.
Nuclease, Proteases, Glycosidases, Lipases,
and Phospholipidases are
the enzymes present
in the Lysosomes.
Functions :
1.
Intra cellular digestion
They digest
carbohydrates, lipids and proteins.
2.Autolysis
;
Cause
self destruction of cell
on insight of disease and they
destroy the cell.
3 Autophagy;
During unfavourable condition their
own cell organelles like
mitochondria and endoplasmic
reticulam.
4. Exocytosis ;
They release
their enzymes outside the cell to digest
other cells.
