E) False 2. The catalytic triad ot‘chymotrypsin contains asp, his anti thr.
B) False 3. Allosteric regulators only inhibit enzyme reactions.
13) False ii. The speciﬁcity pocket for trypsin contains a negatively charged amino acitl.
if.) False Ln , in a diagrammatic depiction ot‘i‘i‘ee energy versus reaction progress. the height of the curve determines the rate ot‘tlte
reaction. An enzyme raises the height ot‘this curve.
