Catalysts, catalyzing agents, activators, inducers, promoters, and accelerators are all synonyms for the word "catalyzer." A catalyst is an essential substance that speeds up a chemical reaction; essentially, it brings about the change. Catalysts work by reducing the energy needed for chemical reactions to occur. It does not get used up during the process, and it can be reused in the transformation of other reactions. Activators are substances that enhance the effect of a catalyst, while inducers are compounds that initiate the action of an enzyme. A promoter or accelerator is a substance that makes a reaction process go faster. All these synonyms have the same effect of catalyzing chemical reactions.
