Rate Of Enzyme Activity And Temperature Many enzymes show curvature in plots of activity versus temperature that is not accounted for by denaturation or unfolding This is explained by macromolecular rate theory A negative
Traditionally the dependence of enzyme activity on temperature has been described by a model consisting of two processes the catalytic reaction defined by GDaggercat and irreversible Oct 1 2010 nbsp 0183 32 A plot of initial t 0 enzyme rates against temperature has an optimum implying that above this optimum increased temperature causes activity loss by conversion of E act to E
