Quizplus · Accepted Answer

According to the information given, the enzyme is taken from a bacterium that lives in a mildly alkaline hot spring at temperatures of 70°C or higher. This indicates that the enzyme functions best at high temperatures and alkaline pH. Looking at the graphs, curves 3 and 5 show high activity at higher temperatures and alkaline pH, so they are the best choices. Curves 1 and 2 appear to have optimal temperatures below 70°C, while curve 4 shows optimal activity at acidic pH, which does not match the conditions in which the enzyme was obtained.
