Microsomes

Microsomes

These are small and sac like structure present in cytoplasm of cell. Endoplasmic reticulum breakdown in fragments, these fragments forms microsomes. When a tissue homogenate at very high speed (10,000 rmp), they can separated. Microsomes contain ribosomes. Ribosome involve in synthesis of protein. Microsomes also contain granular matrix, that  

Contain two enzymes – oxidases and catalases. Microsomes are not present in normal and healthy cells.

Function of microsomes

Oxidases enzyme – This enzyme help to generate hydrogen peroxide.

Catalases enzyme – this enzyme convert hydrogen peroxide to water.
