-Which curves on the accompanying graphs 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?
A) curves 1 and 5 
B) curves 2 and 4 
C) curves 2 and 5 
D) curves 3 and 4 
E) curves 3 and 5

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, as they show optimal activity at high temperatures and alkaline pH levels, consistent with such an environment.
