write a note on micro bodies
Answers
Answer:
A microbody (or cytosome) is a type of organelle that is found in the cells of plants, protozoa, and animals. Organelles in the microbody family include peroxisomes, glyoxysomes, glycosomes and hydrogenosomes. In vertebrates, microbodies are especially prevalent in the liver and kidney.
Structure
Microbodies are present in the cytoplasm of a cell so they are known as cytosomes. They are very small in size ~0.2-1.5 μm and can be seen under the electron microscope.
Some of the common characteristics of microbodies are:
They are vesicular and mostly spherical in shape
They are enclosed in a single membrane of a phospholipid bilayer
The intracellular matrix contains proteins and enzymes
They do not contain separate DNA
Function
Different types of microbodies perform various specific functions.
Microbodies take part in various biochemical reactions in the cell
The enzymes present in microbodies facilitate various essential reactions, e.g. breakdown of fats, amino acids, alcohol, etc.
They are involved in the photorespiration in plants
Detoxification of peroxides occurs in microbodies
