The first type is the oxygen-dependent production of a superoxide,which is an oxygen-rich bacteria-killing substance.The superoxide is converted to hydrogen peroxide and singlet oxygen by an enzyme called superoxide dismutase. Superoxides also react with the hydrogen peroxide to produce hydroxyl radicals, which assist in killing the invading microbe.
