Question

8. (3 pts) The picture below shows one apple, cut in half down the middle. You should notice a significant color change between the right and left sides. Browning in apples is caused by an enzyme called polyphenol oxidase. One of the substrates of this enzyme is oxygen (O2). Why does Side A look different from Side B? Pick ONE of the answers and explain why you chose it. More than one answer may be correct, but some are incorrect. Don't pick a wrong one. a. side A was cut more recently than B b. side A was kept at a warmer temperature than B c. side B was dipped in lemon juice but side A was not. d. side A is an apple and side B is not e. side A was covered with plastic f. side B was submerged in room temp water

Explanation / Answer

Option c and option f are correct.. By dipping apple in lemon juice the enzyme is not able to readily oxidize the apple surface and also cutting or keeping the fruits in water prevents immidiate oxidation..
