1 Enzymes Chapter 6.3 page165

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

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

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

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

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

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

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