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:
“Being a Georgia author is a rather specious dignity, on the same order as, for the pig, being a Talmadge ham.”
—Flannery O’Connor (1925–1964)
“In order to become spoiled ... a child has to be able to want things as well as need them. He has to be able to see himself as a being who is separate from everyone else.... A baby is none of these things. He feels a need and he expresses it. He is not intellectually capable of working out involved plans and ideas like “Can I make her give me...?” “If I make enough fuss he will...?” “They let me do ... yesterday and I want to do it again today so I’ll....””
—Penelope Leach (20th century)
