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

  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 Anaerobe- Lives without the presence of oxygen Giardia

  9. Life at the Extreme! Create a Presentation for Tourists (5 minute) Include: • Location • Challenges of living there • Extremophile- scientific name and relevant information • How it survives- adaptations • Interesting Facts • If we were to go into space, where might we find it?
