Steady-state response to changes in production of X. a) The pattern of linear and saturating responses to changes in [X T ] is shown for the case K A >>K B >> 1. b) The relative sensitivity (see Appendix for definition and analysis) of each component with respect to [X T ] is plotted showing how it peaks above one for free X and BX, but decreases to zero for AX.
