To accurately answer your question, I would need to reference specific details from the graphs you mentioned about enzyme activity, particularly how the activity levels vary with temperature and pH. However, based on general principles of enzyme activity, I can provide guidance on interpreting the statements:
-
Statement a: "The enzyme is very active at approximately 42°C and within a pH range of 2 to 6." - This could potentially be true if the graphs showed high activity at that temperature and that pH range but is likely less common since many enzymes have optimal temperatures around 37°C and often function best at neutral pH levels.
-
Statement b: "The enzyme works best in a pH range of 6 to 8 and at a temperature of approximately 37°C." - This statement is a common observation for many enzymes, especially human enzymes, which typically have an optimal pH near neutral pH (around 7) and a temperature around 37°C.
-
Statement c: "The enzyme functions well at a temperature of 35°C and would be active at any pH value." - While some enzymes can have a broad pH range, the mention of "any pH value" is unlikely to be universally true.
-
Statement d: "The enzyme's activity is greatest at pH 7 and would not be affected by a change in temperature." - Enzyme activity typically is affected by temperature, so the idea that it would not be affected is generally inaccurate.
Given this analysis, if the graphs show high enzyme activity around 37°C and a pH range of 6 to 8, then statement b would be the most accurate response supported by typical enzyme behavior and might reflect the data in the graphs.
Please check the specific details in the graphs to confirm or support this conclusion.
