1. What is the best temperature for this enzyme? 2. What happens when the temperature is too high or too low?

1) Approximately 37 C

2) The enzyme becomes denatured when the temperature is too high. The reaction rate is slowed when the temperature is too low.

Explanation:

1) The highest part of the hump in the graph is where optimal enzymatic activity occurs. At this optimal rate, the temperature appears to be between the 35 C and 40 C, or approximately 37 C.

2) When the temperature is too high, the enzyme becomes denatured as the hydrogen bonds begin to unravel, thus causing the enzyme activity to drastically decrease. When the temperature is too low, the reaction occurs slowly and is not as efficient as it should be due to the reduced amount of collisions between the enzyme and the substrate.

so whats the answer
