Odor response requires extracellular glucose and depends on glycolysis and oxidative phosphorylation. Loose-patch recordings of representative odor responses under five different conditions. Quantification of each set of data are presented under the electrophysiological recordings as boxplots and all data points; statistical significances:*ns, not significant; t test. A, Odor responses under 1 mm glucose (control), after glucose removal and after wash. Boxplots and all data points are shown below the traces; in the boxplot, glucose vs 0-glucose, p < 0.01; 0-glucose vs wash, p < 0.01; N = 15. B, Responses under control solution: control with 10 mm N-acetyl glucosamine (GlcNAc) and control without GlcNAc, below are the boxplots and all data points; control vs GlcNAc, p < 0.05; GlcNAc vs wash, ns; N = 10. C, Responses under control: control with 10 μm rotenone and control without rotenone; below are the boxplots and all data points; control vs rotenone, p < 0.05; rotenone vs wash, ns; N = 12. D, Responses under control, control with 5 μm antimycin A and control without antimycin A; below are the boxplots and all data points; control vs antimycin A, p < 0.05; antimycin A vs wash, p < 0.05; N = 11. E, Responses under control: control-0 glucose and control-0 glucose with 10 μm rotenone; below are the boxplots and all data points; control vs −0 glucose, p < 0.05; 0-glucose vs 0-glucose + rotenone, p < 0.05; control vs 0-glucose + rotenone, p < 0.01.
