How does temperature effect the rate of an enzyme catalyzed reaction as temperature increases, the rate of the enzyme catalyzed reaction also increases because the molecules are moving faster and colliding more frequently after a certain temperature, the reaction rate decreases because the heat starts to denature the enzyme so that it. The effect of temperature on the rates of enzyme-catalyzed reactions is exactly why food is refrigerated a refrigerator's cooler environment slows the enzyme-catalyzed reactions that result in food spoilage of course, freezing food slows those reactions even further other factors that influence the rates of enzyme-catalyzed reactions include surface.

The effects of temperature on enzyme activity the correlation of ph doesn’t seem as clear test tubes 2 and 3, which contained ph 5 and 6 starch, completed the reaction at the same time figure 2 shows the reaction rates of the different ph levels maltose was present in all test tubes.
This optimal temperature is usually around human body temperature (375 o c) for the enzymes in human cells above this temperature the enzyme structure begins to. If the temperature gets too high, it can distort the enzyme, making it unable to function properly in fact, if temperatures got too high, enzymes can become denatured, or undergo a structural change in shape that inhibits function if the change in shape affects the active site, then an enzyme may no longer recognize a substrate with more.

The effect of temperature on the enzyme catalase stephen francis biology 183 abstract this experiment was performed to determine the resultant effect of temperature change on the reaction between the enzyme catalase and hydrogen peroxide. In summary, enzymes work best at their optimum temperature and ph in these optimum conditions, the rate of reaction is at its maximum however, if conditions become too extreme, the enzyme will denature this is because all enzymes are proteins, and the extreme conditions will affect the bonds in their tertiary structures.
