Catalysis is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (/ˈkætəlɪst/). Catalysts are not consumed in the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; mixing, surface area, and temperature are important factors in reaction rate. Catalysts generally react with one or more reactants to form intermediates that subsequently give the final … WebBiological catalysts: the. enzymes. Enzymes are substances found in biological systems that are catalysts for specific biochemical processes. Although earlier discoveries of enzymes had been made, a significant confirmation of their importance in living systems was found in 1897 by the German chemist Eduard Buchner, who showed that the filtered ...
