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:
“Dule and wae for the order sent our lads to the Border;
The English, for ance, by guile won the day:
The Flowers of the Forest, that foucht aye the foremost,
The prime o’ our land, are cauld in the clay.”
