Reapor, Vanessa Biology 111, Section 23 April 17, 2009 Enzymes Exercise 2 2. Explain why there is a decrease in the rate of the reaction at temperatures higher than the optimal temperature for that enzyme. The enzyme begins to denature or in others words, it begins to lose its original structure. The denaturing of an enzyme reduces the rate of the reaction, and the concentration. 3. Offer an explanation of why we use refrigerators. In other words, explain why a partially eaten hamburger gets moldy after a week if left on the kitchen counter, but takes much, much longer to get moldy if kept in a refrigerator. Note that the

Unformatted text preview: temperature of most refrigerators is 4 Degrees Celsius. We use refrigerators because the cold prevents heat from coming in, and keeps our food cold. The cold slows down the bacteria process to keep the food we store longer. 11. Explain how an acidic pH of 3 can affect an enzyme, which in a cell is maintained at pH 7. Be sure to include the effect on bonds and protein structure. Enzymes are dependent upon their shape. Therefore, changes in pH alter the pattern activity of the bonds holding the enzyme its 3-D shape....
