And what this does is it takes two of these hydrogen peroxide molecules react them to form two water molecules as well as a single diatomic oxygen molecule. And these two molecules are completely harmless. They're safe inside our cells. So these two molecules can be used in a variety of different ways. For instance, the oxygen can be used by the electron transport chain to generate ATP molecules and water molecules can be used in a variety of different types of processes. For instance, hydrolysis processes.
