A typical ITC enzyme kinetics experiment. The reaction is initiated when substrate in the syringe is injected into the sample cell containing enzyme. If the reaction is exothermic (endothermic), less (more) feedback power must be supplied to the sample cell to keep it at the same temperature as the reference cell. The instantaneous value of the feedback power is the ITC output.
