Multiple Choice

Compare the two reaction coordinate diagrams below and select the answer that CORRECTLY describes their relationship. In each case, the single intermediate is the ES complex.

A) (a) describes a strict "lock and key" model, whereas (b) describes a transition-state complementarity model.
B) The activation energy for the catalyzed reaction is 5 in (a) and is 7 in (b) .
C) The activation energy for the uncatalyzed reaction is given by 5 + 6 in (a) and by 7 + 4 in (b) .
D) The contribution of binding energy is given by 5 in (a) and by 7 in (b) .
E) The ES complex is given by 2 in (a) and 3 in (b) .
