Cell Structure

2. 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.

3. 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

4. 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.

5. 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.

6. 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

7. 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 X- linked adrenoleukodystrophy and Pero xisome Biogenesis Disorders
