What is the effect of temperature on enzymes isolated from thermophilic organisms?
Options
- AIt damages them
- BIt increases their thermal stability
- CIt improves their efficiency
- DIt does not affect them
Correct answer
B. It increases their thermal stability
Step-by-step solution
Inorganic catalysts work efficiently at high temperatures and high pressures, while enzymes get damaged at high temperatures (say above 40°C). Enzymes isolated from organisms who normally live under extremely high temperatures (e.g., hot vents and sulphur springs), are stable and retain their catalytic power even at high temperatures (upto 80°-90°C). Thermal stability is thus an important quality of such enzymes isolated from thermophilic organisms.
