       About superoxide

       The superoxide ion is an anion with an unpaired electron on one
       of its oxygen atom. Because of the unpaired electron, the
       superoxide ion is very reactive.
       Superoxide is formed in cells during the electron transport
       chain. When formed in the cell, the superoxide ion attacks
       organic molecules, such as DNA, proteins and lipids, damaging
       the cell. To protect the cell from the superoxide, superoxide
       dismutase is produced to decompose the superoxide ion into
       hydrogen peroxide and oxygen. However, hydrogen peroxide is
       still toxic to the cell, so catalase is produced to decompose
       the hydrogen peroxide into oxygen and water.
