External quality traits include tuber size and shape as well as resistance against mechanical stress during and after harvest. The hydrogen ion concentration (pH level), has the effect on the enzyme potato catalase in that it alters the charges on the acidic and basic groups of the protein, altering the ionic charges causes the ionic bonds to break.
