Table 1.

Logarithmic gain with respect to O2 and mean parameter sensitivities for all phenotypic regions. Each logarithmic gain represents the percentage change in the steady-state value of the dependent variable, x2 (inactive FNR) or x3 (active FNR), in response to a percentage change in the value of the independent variable x8 (O2). Each parameter sensitivity represents the percentage change in the steady-state value of the dependent variable, x2 (inactive FNR) or x3 (active FNR), in response to a percentage change in the value of one of the parameters that define the system. The mean parameter sensitivity across all the parameters is reported here to show regions in which there is a tendency to amplify/attenuate small changes to the values of the parameters.
