catalysis

 [kah-tal´ĭ-sis]

increase in the velocity of a chemical reaction or process produced by the presence of a substance that is not consumed in the net chemical reaction or process; negative catalysis denotes the slowing down or inhibition of a reaction or process by the presence of such a substance. adj., adj catalyt´ic.

ca·tal·y·sis

(kă-tal'i-sis),
