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:
“It is well within the order of things
That man should listen when his mate sings;
But the true male never yet walked
Who liked to listen when his mate talked.”
—Anna Wickham (1884–1947)
“We enter parliament in order to supply ourselves, in the arsenal of democracy, with its own weapons.... If democracy is so stupid as to give us free tickets and salaries for this bear’s work, that is its affair.... We do not come as friends, nor even as neutrals. We come as enemies. As the wolf bursts into the flock, so we come.”
—Joseph Goebbels (1897–1945)
