WebDec 20, 2007 · The effects of pH on the rates of enzyme-catalyzed reactions are very important because they yield information on the pKs of acidic groups in the enzymatic site and the various enzyme-substrate complexes. But many enzyme-catalyzed reactions produce or consume hydrogen ions in a way that cannot be explained with pKs. Webperoxidase reaction is an important source of oxygen for routine use in some metabolic pathways. Like the oxygen-carrying protein hemoglobin, peroxidase has a heme group at its active site; an iron atom in the heme is essential for the enzyme to function. The reaction rate for an enzyme reaction is the speed at which an enzyme converts
