catalyze

v. accelerate the rate of a chemical reaction by catalysis; cause change while remaining unaffected (also catalyse)

In chemistry and biology, catalysis is the acceleration (increase in rate) of a chemical reaction by means of a substance called a catalyst, which is itself not consumed by the overall reaction. More generally, one may at times call anything that accelerates a process, a "catalyst" (for example, a "catalyst for political change"). The word is derived from the Greek noun κατάλυσις, related to the verb καταλύειν, meaning to annul or to untie or to pick up.

Verb
1. change by catalysis or cause to catalyze
(synonym) catalyse
(hypernym) change state, turn
(derivation) catalyst, accelerator
(classification) chemistry, chemical science

 Say it 
A substance which increases the rate of a chemical reaction without being consumed or produced by the reaction. Catalysts speed both the forward and reverse reactions, without changing the position of equilibrium . Enzymes are catalysts for many biochemical reactions.
