One of the laboratory experiments demonstrated that Glucose concentration can be measured by the o-toluidine assay as well as the hexokinase assay. If a sample contained 10 mg/ml glucose and 10 mg/ml mannose, the o-toluidine assay would calculate a sugar concentration a) twice the concentration calculated by the hexokinase assay b) half the concentration of the hexokinase assay c) the same as that produced by the hexokinase assay d) 10 times the concentration produced by the hexokinase assay e) 1/10 the concentration produced by the hexokinase assay O a O b
