Question

3. the algae in thermal springs, such as old faithful in yellowstone park, have temperatures above 100c. Does this mean the optimal temperature for different enzymes in different organisms may vary?

Answer 1

The optimal temperature for different enzymes in different organisms may vary and it happens because some of the organisms change their proteins via mutations in order to adapt to a certain environment. For example, algae have developed a special type of heat resistance protein that helps them survive in these extreme conditions.
