Enzyme Lab Catalase Blood & Liver H2O2 Toxic H2O2 +catalase= H2O + O2

Properties of Enzymes Proteins Catalysts Speed reactions Work fast Denature at high temp

Enzyme-Substrate complex Active site = where the substrate ( reaction molecule) connects to enzyme Active Site Substrate Enzyme

Enzymes remain unchanged! Before Enzymes are not used up No more substrate = end to the reaction Synthesis or Decomposition reactions After

Lock & Key Model One enzyme for every substrate unique fit Enzyme

Enzymes are pH specific Different enzymes Different body areas Different optimum pH Examples: Stomach= acid pH Mouth= basic pH Blood Mouth Stomach

Enzymes are temperature dependent…... Most at body temperature 37oC Denature at high temperatures
