The rate acceleration conferred by enzymatic catalysis is often enormous—as much as 1017-fold increase in rate over the uncatalysed reaction in the case of orotate decarboxylase (78 million years without the enzyme, 18 milliseconds with the enzyme).
Den accelerationsgrad som enzymerna katalyserar är ofta enorm - upp till 1017-faldigt den okatalyserade reaktionen hos orotat dekarboxylas (78 miljoner år utan enzymet, 18 millisekunder med enzymet).
