When exposed to oxygen the enzyme catalyzes the reaction creating melanins ( brown pigments) on the fruit.
Investigating different browning reactions: teacher notes
WebCatechol oxidase (also known as catecholase) is an enzyme present in most fruits and vegetables. It facilitates the browning of cut or bruised produce by catalyzing a reaction between the substrate molecule catechol and atmospheric oxygen (O2). The ultimate product of this oxidation reaction is polyphenol, a brown compound that accumulates … WebHYPOTHESIS EXAMPLE: Since all citric fruit contains citric acid, then covering apple slices with the juice of any type of citric fruit will prevent the slices from browning.
