PEROXISOMES
ISOLATED FROM;
➤DE-DUVE AND COWORKERS ISOLATED IN 1965 PARTICLES FROM LIVER CELLS AND
OTHER TISSUES WHICH WERE ENRICHED WITH SOME OXIDATIVE ENZYMES,
★SUCH AS;
★PEROXIDASE,
★CATALASE,
GLYCOLIC ACID OXIDASE AND SOME OTHER ENZYMES.
WHY WE CALLED IT PEROXISOMES??
➤THE NAME PEROXISOME WAS APPLIED BECAUSE THIS ORGANELLE IS SPECIFICALLY
INVOLVED IN THE FORMATION AND DECOMPOSITION OF HYDROGEN PEROXIDE IN
THE CELL.
CYTOPLASMIC ORGANELLE;
➤THESE ARE SINGLE MEMBRANE ENCLOSED CYTOPLASMIC ORGANELLE FOUND
BOTH IN ANIMAL AND PLANT CELLS.
IN ANIMAL CELL
IN PLANT CELL
CONTAINS
➤THESE ARE CHARACTERIZED BY CONTAINING H2O2-PRODUCING OXIDASES AND
CATALASE.
DIAMETER;
➤THEY ARE APPROXIMATELY 0.5 UM IN DIAMETER.
FOUND IN;
➤THEY HAVE ALSO BEEN FOUND IN PROTOZOA, YEAST AND MANY CELL TYPES OF
HIGHER PLANTS.
