A group of students conducts research on enzyme activity and collects the data shown in the graphs.
There are two graphs. The first graph has increasing enzyme activity on the y-axis and temperature, in Celsius, on the x-axis. The line increases at a steady rate until about 37 degrees Celsius, then quickly decreases. The second graph has increasing enzyme activity on the y-axis and pH on the x-axis. The line slowly increases until there is a pH of between 6 and 8, then starts to decrease.
Which statement is supported by the evidence in the graphs?
A.
The enzyme is very active at approximately 42°C and within a pH range of 2 to 6.
B.
The enzyme functions well at a temperature of 35°C and would be active at any pH value.
C.
The enzyme works best in a pH range of 6 to 8 and at a temperature of approximately 37° C.
D.
The enzyme's activity is greatest at pH 7 and would not be affected by a change in temperatur
