  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
