Effect of Temperature on Enzyme Activity
A group of students performed an enzyme assay at various temperatures. Which of the following best explains why the enzyme activity was lowest at 50 degrees Celsius?
 |
A
High temperatures change the shape of the active site and increase the enzyme's ability to recognize the substrate.
B
High temperatures change the shape of the active site and decrease the enzyme's ability to bind to the substrate.
C
High temperatures change the shape of the active site and increase the reaction rate.
D
High temperatures change the shape of the active site and increase the amount of energy necessary to drive the chemical reaction.
E
High temperatures change the shape of the active site and decrease the amount of energy released by the chemical reaction.
