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

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

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

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

7. Chemical Extremes Acidophile Alkaliphile Halophile Dead Sea Mono Lake- soda lake

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