To determine which statement is supported by the evidence in the graphs, we would need to analyze the data regarding enzyme activity in relation to temperature and pH. Since I don't have access to the graphs themselves, I will guide you on how to evaluate the statements based on typical enzyme behavior.
-
Statement a: "The enzyme functions well at a temperature of 35°C and would be active at any pH value."
- Evaluate temperature and pH data. If the graphs show a decline in activity at extreme pH values, this statement would not be supported.
-
Statement b: "The enzyme's activity is greatest at pH 7 and would not be affected by a change in temperature."
- If the graphs display maximum activity at pH 7 but show a noticeable change in activity with temperature variations, this statement is not supported.
-
Statement c: "The enzyme is very active at approximately 42°C and within a pH range of 2 to 6."
- Check if the enzyme activity peaks at 42°C and if there is significant activity within the pH range of 2 to 6. If not, this statement would be unsupported.
-
Statement d: "The enzyme works best in a pH range of 6 to 8 and at a temperature of approximately 37° C."
- Look for maximum activity within this pH range and at about 37°C. This statement would be supported if the graphs show activity peaking at these values.
Based on your observation of the graphs, choose the statement that best matches the data presented. If possible, please provide a description of the graphs to facilitate a more accurate analysis.
