WebThe effect of Temperature on Enzyme •The rate of an enzyme catalyzed reaction is affected by changes in temperature •Each enzyme has a temperature that it works optimally in called (Optimum Temperature) •For most enzymes, the optimum temperature is at or above the temperature of the cells in which the enzyme is found in vivo. WebThis is because a higher kinetic energy will result in more frequent collisions between the enzymes and substrates. At an optimal temperature (may vary for different enzymes), the rate of enzyme activity will be at its peak. Higher temperatures will cause enzyme stability to decrease, as the thermal energy disrupts the enzyme’s hydrogen bonds.

WebMost enzymes will become denatured at very high temperatures. Although increased temperatures can cause enzymes to work more quickly, if the temperature gets too high the enzyme stops working. If the temperature around an enzyme gets too high, the enzyme loses its shape, which is known as denaturation, and ceases to work. WebBecause active sites are finely tuned to help a chemical reaction happen, they can be very sensitive to changes in the enzyme’s environment. Factors that may affect the active site and enzyme function include: Temperature. A higher temperature generally makes for higher rates of reaction, enzyme-catalyzed or otherwise.
