Answer
Thermophiles and psychrophiles are microorganisms that thrive in extreme temperature environments.
Solution
a
Thermophiles: These are organisms that thrive at relatively high temperatures, typically between 45°C and 122°C. An adaptation that allows thermophiles to live in such extreme environments is the presence of heat-stable enzymes and proteins that do not denature at high temperatures
b
Psychrophiles: These are organisms that thrive at very low temperatures, typically below 15°C. An adaptation that allows psychrophiles to survive in cold environments is the presence of cold-active enzymes and antifreeze proteins that prevent ice crystal formation within their cells
Key Concept
Thermophiles and psychrophiles are adapted to extreme temperatures.
Explanation
Thermophiles have heat-stable enzymes, while psychrophiles have cold-active enzymes and antifreeze proteins.
