catalysis /ca·tal·y·sis/ (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 c. denotes the slowing down or inhibition of a reaction or process by the presence of such a substance.catalyt´ic

catalysis
[kətal′əsis]
Etymology: Gk, katalein, to dissolve
an increase in the rate of a chemical reaction that is caused by a substance that is neither permanently altered nor consumed by the reaction. Compare negative catalysis. See also catalyst. catalytic. adj., catalyze, v.
catalysis (k
tal´sis),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.
catalyst, which takes no part in the reaction and remains unchanged.
catalysis
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.
