Problem

Suppose that, in the absence of a catalyst, a certain biochemical reaction occurs x times per second at normal body temperature (37 oC). In order to be physiologically useful, the reaction needs to occur 5500 times faster than when it is uncatalyzed.

By how many kJ/mol must an enzyme lower the activation energy of the reaction to make it useful?
