Why do apples turn brown?

Answer by  Sinefey (457)

It happens when the enzyme polyphenol oxidase gets exposed to oxygen. Cutting the apple (or potato) basically slices some of those enzymes open and exposes them to oxygen, turning brown.

iron containing chemicals inside apple cells react with oxygen in the air. that is oxidation happened in that part. the chemical reaction between air and the chemicals inside the apple is the reason which turn brown

Apples turn brown when they come into contact with the air. Lemon juice helps, but for best results wait until right before serving to cut them.

there is no proof that it is oxygen that the apple reacts with, it could be the carbon dioxide, the nitrogen or the oxygen in the air.
