Temperature : Increases in temperature will speed up the rate of nonenzyme mediated reactions, and so temperature increase speeds up enzyme mediated reactions, but only to a point. When heated too much, enzymes (since they are proteins dependent on their shape) become denatured. When the temperature drops, the enzyme regains its shape. Thermolabile enzymes, such as those responsible for the color distribution in Siamese cats and color camouflage of the Arctic fox, work better (or work at all) at

Unformatted text preview: lower temperatures. Concentration of substrate and product also control the rate of reaction, providing a biofeedback mechanism. Activation , as in the case of chymotrypsin, protects a cell from the hazards or damage the enzyme might cause. Changes in pH will also denature the enzyme by changing the shape of the enzyme. Enzymes are also adapted to operate at a specific pH or pH range....
