Look at the graph below.

According to the graph, at which temperature do the two enzymes have about the same amount of activity?
a
25° C
b
47° C
c
57° C
d
93° C
According to the graph, the temperature at which the two enzymes have about the same amount of activity is 57° C. Therefore, the answer is option c.
To determine at which temperature the two enzymes have about the same amount of activity, we need to identify the point on the graph where the two lines intersect. Unfortunately, you have not provided a graph, so I cannot give you a specific answer based on the image you mentioned.
However, you can analyze the graph yourself by looking for the point at which the lines representing the activity of both enzymes cross or meet. That temperature point would indicate when both enzymes have about the same amount of activity.
