Molecular degradation during the decomposition of organs and tissues is catalyzed by enzymes. The cooling to adequate temperatures of some organs and tissues destined for transplantation reduces that enzyme activity and thus decreases the natural decomposition process. By the same rationale, the cooling reduces the metabolic work of cells and prevents the breakdown of their own structures to obtain energy. A subsequent increase in temperature reverts the denaturation of enzymes, allowing the organs and tissues also preserved by other specific techniques to be grafted into the receptors.
