Cooling of tissues and organs for medical transplants

Question

How is the cooling of tissues and organs for medical transplants related with the consequence of temperature on enzymatic reactions?

Answer 1

The molecular degradation throughout the decomposition of tissues and organs is catalyzed by enzymes. The cooling to sufficient temperatures of certain tissues and organs destined for transplantation decreases that enzyme activity and therefore lessens the natural decomposition procedure. By similar rationale, the cooling decreases the metabolic work of cells and saves degradation of their own structures to receive energy. Elevation of temperature afterward reverts denaturation of enzymes and the tissues and organs as well preserved by other particular techniques might be grafted into the receptors.
