|
|
|
their enzymes are insensitive to temperature
|
|
|
they use molecules other than proteins as their main catalysts
|
|
|
their enzymes have high optimal temperatures
|
|
|
they are able to maintain an internal temperature much cooler than that of the surrounding water
|
Detailed explanation-1: -Some bacteria are metabolically active in hot springs because they are able to maintain a lower internal temperature. their enzymes have high optimal temperatures. high temperatures make catalysis unnecessary.
Detailed explanation-2: -they are able to maintain a lower internal temperature.
Detailed explanation-3: -The optimum temperature for enzyme activity was between 60°C and 80°C. A reduction in enzyme activity was observed at values above 80°C. The enzyme extract retained 100% of initial activity when incubated for 45 min at 100°C respectively (Fig. 6).
Detailed explanation-4: -If an enzyme is added to a solution where its substrate and product are in equilibrium, what will occur? The free energy of the system will change.
