Chapter 4
Cell Structure
WHAT ARE MICROBODIES?
Eukaryotic
cells that contain a variety of
enzyme-bearing, membrane enclosed
vesicles.
Found in the cells of plants, animals,
fungi, and protists.
WHAT IS THE STRUCTURE OF
MICROBODIES?

A vesicle with a spherical shape.

Only visible with the use of an electron
microscope.

Surrounded by a single phospholipid bilayer
membrane

Contain a matrix of intracellular material
including enzymes and other proteins
TYPES OF MICROBODIES
 Peroxisome-
a type of microbody that
functions to help the body break down
large molecules and detoxify hazardous
substances
 It contains oxidative enzymes and
catalysts.
TYPES OF MICROBODIES
CONTINUED..
 Glyoxysomes
are specialized peroxisomes
found in plants and mold
 Help
to convert stored lipids into
carbohydrates so they can be used for plant
growth.
WHAT IS THE FUNCTION OF
MICROBODIES?
 To
isolate particular chemical
activities from the rest of the cell
 The distribution of enzymes into
microbodies is one of the principal
ways eukaryotic cells organize their
metabolism
DISEASES ASSOCIATED WITH
MICROBODIES

Peroxisomal disorders are a class of
medical conditions that typically affect
the human nervous system as well as
many other organ systems

Two common examples are Xlinked adrenoleukodystrophy and Pero
xisome Biogenesis Disorders
