What happens when you mix hydrogen peroxide and iodine and sugar?

Hydrogen peroxide is a toxic substance that is sometimes made in our cells due to some chemical reactions. It is poisonous so cells produce an enzyme called 'Catalase' which break down hydrogen peroxide to water and oxygen. Because catalase is in our blood, if hydrogen peroxide is added to it, it breaks down: Blood + H2 O2(hydrogen peroxide) --changes to-- H2O (water) + O2 (oxygen).
