A group of students conducts research on enzyme activity and collects the data shown in the graphs.
Which statement is supported by the evidence in the graphs?
a
The enzyme functions well at a temperature of 35°C and would be active at any pH value.
b
The enzyme works best in a pH range of 6 to 8 and at a temperature of approximately 37° C.
c
The enzyme's activity is greatest at pH 7 and would not be affected by a change in temperature.
d
The enzyme is very active at approximately 42°C and within a pH range of 2 to 6.
The answer supported by the evidence in the graphs is b) The enzyme works best in a pH range of 6 to 8 and at a temperature of approximately 37° C.
The statement supported by the evidence in the graphs is:
b) The enzyme works best in a pH range of 6 to 8 and at a temperature of approximately 37° C.
From the graph on the left, we can see that the enzyme activity is the highest within the pH range of 6 to 8. From the graph on the right, we can see that the enzyme activity is also highest at a temperature of approximately 37°C. Therefore, the evidence in the graphs supports statement b.
