WebThe Central Role of Enzymes as Biological Catalysts A fundamental task of proteins is to act as enzymes —catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins. WebThe catalyst can be either iron (II) or iron (III) ions which are added to the same solution. This is another good example of the use of transition metal compounds as catalysts because of their ability to change oxidation state. For the sake of argument, we'll take the catalyst to be iron (II) ions. simple filter for water
