What is a justification for a hypothesis stating that copper ion is the necessary cofactor in the catechol oxidase reaction? In other words, what evidence based on observation is there to support this claim? Hints: Citric Acid and EDTA bind to copper ions to inhibit cofactor ability. In the catechol oxidase reaction, benzoquinone is produced. What does benzoquinone do in fruits and plants? How does it preserve food? Does citric acid have this same effect?
