.
These were first observed by
Rhodin (1954
) in kidney cells of
rats
and were named peroxisomes by
Christian de Duve in 1965.
Peroxisomes
are microbodies having a diameter of 0.5 - 1.5 nm.
Peroxisome structure -
These are bounded by single membranes and enclosed enzymes
peroxidases
and
catalases
,
And carry out oxidative reactions using molecular oxygen.
They produce hydrogen Peroxide through their degradative activity.
