WebBecause most animal enzymes rapidly become denatured at temperatures above 40°C, most enzyme determinations are carried out somewhat below that temperature. Over a period of time, enzymes will be deactivated at even moderate temperatures. Storage of enzymes at 5°C or below is generally the most suitable. WebThis alteration can be caused by the development of copper-catalase complexes or by copper ions oxidizing the enzyme. 5. Because the heat caused the enzyme's protein structure to denature or unfold, which can disrupt the active site and hinder the enzyme from forming a bond with its substrate, the heat-treated enzyme most likely behaved ... selling myself down the riverWebThis occurs because heat increases the kinetic energy and causes the molecules to vibrate so rapidly and violently that the bonds are disrupted.
