In this study, the effects of yeast fermentation and … WebGlucose oxidase (GOD) is a typical flavin enzyme with flavin adenine dinucleotide (FAD) as redox prosthetic group. Its biological function is to catalyze glucose to form gluconolaction, while the enzyme itself is turned from GOD (FAD) to GOD (FADH2). GOD was used to prepare biosensors in extensive fields. Webconcentrations of glucose oxidase and glucose, pH at 7.0 and temperature at 28oC. The results show that the addition of sodium perchlorate has a positive effect on the reaction rate. This may be due to changes in the conformational state of the protein which tends to make the oxygen to be more accessible. Effect of temperature: The glucose oxidase darwin nutrition
