Answer 2

Answer:

There is something in apples called PPO (polyphenol oxidase), which is an enzyme. Enzymes are things that do all the work to make sure cells can live their life. Once you cut into an apple you are opening up some of the cells inside it. The PPO enzyme reacts to the oxygen in the air and starts to turn the apple brown.
