questions).
-Which curves on the graphs provided may represent the temperature and pH profiles of an enzyme taken from a bacterium that lives in a mildly alkaline hot springs at temperatures of 70°C or higher?

Question

Quizplus · Accepted Answer

Curves 3 and 5 likely represent the temperature and pH profiles of an enzyme from a bacterium in mildly alkaline hot springs. Curve 3 would show high activity at temperatures around 70°C or higher, indicating thermal stability. Curve 5 would show optimal activity at a pH above 7, consistent with a mildly alkaline environment.
