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),
The effect that a catalyst exerts on a chemical reaction.
[G. katalysis, dissolution]

catalysis (kətal´əsis),

n the increase in rate of a chemical reaction, induced by a substance called a
catalyst, which takes no part in the reaction and remains unchanged.

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.

covalent catalysis
one type of enzyme reaction with substrates to form very unstable, covalently joined enzyme-substrate complexes which undergo further reaction.
