In the presence of oxygen, the enzyme TYROSINASE catalyzes the oxidation of DOPA (3,4-dihydroxyphenylalanine), producing dopaquinone. Dopaquinone spontaneously converts into dopachrome (a dark orange/brown molecule).Here is a simple diagram that illustrates this reaction:DOPA + O2 ⇒⇒⇒TYROSINASE⇒⇒⇒ Dopaquinone ≈ Dopachrome (orange/brown)Which of the following statements best describes tyrosinase?A. A product of an enzymatic reactionB. A polypeptide chain with active sites that bind DOPA and OxygenC. A substrate that is converted to dopachromeD. A coenzyme that binds to oxygenE. An inhibitor that prevents oxidation
