Traditionally, the dependence of enzyme activity on temperature has been described by a model consisting of two processes: the catalytic reaction defined by δg dagger cat, and irreversible inactivation defined by δg dagger inacthowever, such a model does not account for the observed temperature-dependent behaviour of enzymes, and a new model has been developed and validated.
