Question 10 A group of students conducts research on enzyme activity and collects the data shown in the graphs . Enzyme activity Enzyme activity- 10 15 20 25 30 35 40 45 50 Temperature 4 6 8 10 PH Which statement is supported by the evidence in the graphs ? a Oc The enzyme works best in a pH range of 6 to 8 and at a temperature of approximately 37 The enzyme is very active at approximately 42C and within a pH range of 2 to 6 The enzyme functions well at a temperature of 35C and would be active at any pH value The enzyme's activity is greatest at pH 7 and would not be affected by a change in temperature .

Answer 1

To determine which statement is supported by the evidence in the graphs, we need to analyze each option based on the enzyme activity data:

1. The enzyme works best in a pH range of 6 to 8 and at a temperature of approximately 37°C: This statement would be supported if the graphs show high enzyme activity around pH 6 to 8 and temperature near 37°C.

2. The enzyme is very active at approximately 42°C and within a pH range of 2 to 6: This would be supported if the graphs indicate high activity at 42°C and low pH levels.

3. The enzyme functions well at a temperature of 35°C and would be active at any pH value: This would need evidence of consistent activity at 35°C regardless of pH changes.

4. The enzyme's activity is greatest at pH 7 and would not be affected by a change in temperature: This statement would be valid if the data shows peak activity at pH 7 with relatively stable activity across a range of temperatures.

Based on the provided information, the first option aligns best with the typical behavior of enzymes, which often have specific optimal pH and temperature ranges. If the graphs indeed show high activity around pH 6 to 8 and a temperature near 37°C, this statement is supported.

In summary, select the statement that aligns best with the data shown in the graphs, particularly focusing on the optimal conditions for enzyme activity regarding pH and temperature.
