In the presense of catechol oxidase, catechol + ½O2 à benzoquinone + H2O. The substrates of catechol oxidase, catechol and oxygen, reac! t with each other inwardly the active site of an enzyme. The product realiseed in this reaction is benzoquinone and water. (http://darwin.baruch.cuny.edu/darwin/bio1003/enzymes.html) Catechol Oxidase is an enzyme in potato extract that goes through an oxidization reaction with catechol and converts into benzoquinone.
