Zero Order
For zero-order reactions, the reaction rate is independent of the concentration of a reactant, so that changing its concentration has no effect on the speed of the reaction. This is true for many enzyme-catalyzed reactions, provided that the reactant concentration is much greater than the enzyme concentration which controls the rate. For example, the biological oxidation of ethanol to acetaldehyde by the enzyme liver alcohol dehydrogenase (LADH) is zero order in ethanol.

Famous quotes containing the word order:
“That matches are made in heaven, may be, but my wife would have been just the wife for Peter the Great, or Peter Piper. How would she have set in order that huge littered empire of the one, and with indefatigable painstaking picked the peck of pickled peppers for the other.”
—Herman Melville (1819–1891)
“Play not with paradoxes. That caustic which you handle in order to scorch others may happen to sear your own fingers and make them dead to the quality of things.”
—George Eliot [Mary Ann (or Marian)
