How does fruit react to oxygen?

Oxygen in the air can cause sliced fruit to brown, a process called enzymic browning (an oxidation reaction). Phenols and the enzyme phenolase are found in the cells of the apple, and when these are exposed to oxygen in the air, for example through slicing, the oxygen causes a reaction.

I'm fine with them being them but when they try to influence me or change public policy then i have a problem
