The enzymatic cycle of glucose oxidases (GOx) and the production of hydrogen peroxide. In the above system, GOx which is a flavin adenine dinucleotide (FAD)-dependent enzyme oxidises β-d-glucose to gluconolactone through a process that involves the transfer of two protons and two electrons from the substrate to the FAD cofactor. By passing these to oxygen, hydrogen peroxide is formed locally within the surrounding environment.
