 The response curve for one driver can depend on other drivers, here exemplified for temperature and pH in the central panel. This interaction causes rates as well as optima to change with pH  and temperature , indicated by the coloured lines.  Impacts of multiple drivers on processes can be additive , synergistic  or antagonistic , that is, the cumulative effects of two  drivers are equal to, larger than or smaller than the sum of their individual effects, respectively. Potential experimental outcomes affected by additive, synergistic and antagonistic interactions are shown for scenarios where drivers increase rates , decrease rates  or cause opposite responses , showing how experimental outcomes can mask these mechanistic interactions.  .
