To determine which statement is supported by the evidence in the graphs, we need to analyze the potential relationships depicted in the graphs regarding enzyme activity in relation to pH and temperature. However, since I can't see the graphs directly, I will evaluate the options based on typical enzyme behavior.
-
Option A suggests that the enzyme's activity is greatest at pH 7 and would not be affected by a change in temperature. Typically, enzymes do have optimal pH and temperature conditions, so this statement might be misleading.
-
Option B states the enzyme functions well at a temperature of 35°C and would be active at any pH value. Enzymes usually have a preferred pH range, so this statement is likely inaccurate if there is a specific pH range shown in the graphs.
-
Option C claims the enzyme is very active at approximately 42°C and within a pH range of 2 to 6. Higher temperatures can often lead to denaturation, so this statement could be true, but we need to see the graphs.
-
Option D asserts the enzyme works best in a pH range of 6 to 8 and at approximately 37°C. This aligns well with typical enzyme activity, as many enzymes work optimally around neutral pH levels and in physiological temperature ranges.
Based on general knowledge of enzyme activity, without specific data from the graphs, Option D is likely the most accurate statement. However, you should confirm this by checking the graphs for pH and temperature data to verify which statement aligns with observed trends in enzyme activity.
