What organic compounds are found in the cells of apples, and when these are exposed to oxygen in the air, for example through slicing, the oxygen causes reaction?
 

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. Phenols

  • This process occurs due to the action of an enzyme called polyphenol oxidase, which is normally found in many plant tissues. When you cut an apple, some cells also open. After this this enzyme is able to reach the oxygen present in the air and the process of browning of the apple starts.
