Not all enzymes have an optimum temp of around 40 degrees celcius. Find out where reactions involving enzymes:

would take place at very high temperatures

would take place at very low temperatures

i've tried looking on the internet, but I get a lot of results on how high and low temperatures effect enzymes in general. If you could help me that would be greatly appreciated!

Thank you!

The above site lists a specific enzyme. I'm not sure this source lists the actual enzyme for low T. If not, go to www.google.com and type in low temperature enzymes. (By the way, note the correct spelling of Celsius.)

To determine where reactions involving enzymes would take place at very high or low temperatures, we need to consider extremophile organisms. Extremophiles are organisms that thrive in extreme environments, such as high heat or low temperatures. These organisms have adapted to function and carry out metabolic reactions under these extreme conditions. By studying extremophiles, scientists can identify enzymes that are highly stable and active at extreme temperatures.

For reactions involving enzymes at very high temperatures, or in hot environments, we can look at thermophilic organisms. Thermophilic enzymes are active at temperatures above 50 degrees Celsius, and some can function optimally even at temperatures exceeding 100 degrees Celsius. These enzymes have evolved to withstand the denaturing effects of high temperatures.

Some examples of extremophiles that thrive at high temperatures include bacteria from hydrothermal vents deep in the ocean, such as Thermus aquaticus, which is known to produce a heat-resistant enzyme called Taq polymerase, widely used in DNA amplification techniques like PCR (polymerase chain reaction).

On the other hand, for reactions involving enzymes at very low temperatures, or in extremely cold environments, we can look at psychrophilic organisms. Psychrophilic enzymes are active at temperatures near or below freezing point. These enzymes remain functional and stable despite the low temperatures.

One example of a psychrophile is the bacterium Psychrobacter cryohalolentis, which is found in Arctic and Antarctic regions. It produces cold-adapted enzymes that are active in sub-zero temperatures.

In summary, reactions involving enzymes at very high temperatures would take place in thermophilic organisms, while reactions involving enzymes at very low temperatures would take place in psychrophilic organisms. By studying these extremophiles, scientists gain insights into how enzymes function under extreme temperature conditions and may even discover new applications for industries that require extreme temperature stability, such as biotechnology and bioremediation.
