                   But what does an enzyme do to establish such speed? As we have

               already seen, enzymes reduce the energy needed for a reaction to take
               place. But just what is this activation energy? We can describe it thus:
               In terms of energy, under normal conditions, the most suitable mole-
               cule for carbon to combine with is carbon dioxide. When these two are
               present in the same environment they will act on one another and have
               a combustive effect. Yet even though these two substances are present
               in the same living body, they never combust. Although the book you
               are holding contains carbon and is in constant contact with carbon
               dioxide, it never suddenly bursts into flames. The reason for this is that

               the carbon-based molecules in living organisms and books have stable
               structures, and in the absence of new energy (i.e., heat) from outside,
               they cannot break those bonds and suddenly combust. New energy ar-
               riving from the outside in such a way as to destabilize the structure in
               question is called "activation energy." The activation energy needed to
               impair the stable structure we are discussing here—in other words for
               this book to ignite—is a burning match. For the molecules in the watery
               solution inside the cell, that heat energy is released as a result of the col-

               lisions of molecules around them. Enzymes are responsible for reduc-
               ing the considerable energy released during these collisions.
                   In order to measure the speed of enzymes' activity, biochemists
