Figure 3

Apparent ODCs for Mb in perfused muscle at various steady-state O2 uptake levels. PO2 is the same as in Fig. 2. A, ODCs as O2 saturation (Y) plotted against log PO2. The lines were calculated from the Hill equation (see below). Each ODC was obtained from three animals (three muscle preparations). Symbols (mean ± SD) express observed points and their meaning is the same as in Fig. 2. The lines without symbols are the ODCs for Mb in non-respiring muscle [21]. B, Apparent ODCs as expressed by the Hill plot which is based on the linearized Hill equation [25]: log {Y/(1 - Y)} = n (log PO2 - log PY50). The slope of the plot (n) was constant and expressed as napp in the present paper. The napp and intercept values obtained from the Hill plots are listed in Table 2.
