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

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
