catalytic

adj. causing catalysis, causing an acceleration in the rate of chemical reactions

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.
