11. This means sometimes radical mechanisms are involved, especially in redox reactions . 12. In order to work as a catalyst, GOx requires a redox reactions ). 13. Half-reactions are often used as a method of balancing redox reactions . 14. The working mechanisms of pseudocapacitors are redox reactions , intercalation and electrosorption. 15. In a redox reaction , this heat is a useless byproduct lost to the system. 16. In this way, ferredoxin acts as an electron transfer agent in biological redox reactions . 17. The Creutz Taube ion illustrates the advantages of ruthenium complexes for examining redox reactions . 18. The iron atom from this haem group undergoes redox reactions : 19. They are found either as subunits of larger enzymatic complexes that catalyze redox reactions . 20. Combustion, many explosives, and organic redox reactions involve atom-transfer reactions.
