What is an extremophile?
Microbes that live where nothing else can
Extremozymes- enzymes that work
under extremes

What is an enzyme?Large biological molecule responsible
chemical reactions that sustain life

Enzymes at extremes
Extreme temperatures cause proteins to denature, which is why fevers can be
dangerous.
• Temperature• pH• Salt concentration

Extremophile“Extreme” “loving”
Thermophiles- high temperatures
Psychrophiles- low temperatures

More Extremophiles…
Endolith- Lives inside rocks or pores of minerals
Giardia
Anaerobe- Lives without the presence of oxygen

Life at the Extreme!
Create a Presentation for Tourists (5 minute)Include:LocationChallenges of living thereExtremophile- scientific name and relevant
informationHow it survives- adaptationsInteresting FactsIf we were to go into space, where might we
find it?
