Question

Quizplus · Accepted Answer

When an apple slice turns brown, it is due to oxidation. When the enzymes in the apple come in contact with oxygen in the air, a chemical reaction occurs causing the apple to turn brown. This is a natural process that occurs over time and can be slowed down by reducing the apple's exposure to air.
