  1. Enzymes: Biological Catalysts www.assignmentpoint.com

  2. Catalysts • speed up the rate of the reaction. • lowers the energy input required for a chemical reaction to happen • remains unchanged at the end of the reaction skool www.assignmentpoint.com

  3. Enzymes • Enzymes are Biological catalysts • Enzymes control chemical reactions that take place in the cytoplasm. • http://programs.northlandcollege.edu/biology/Biology1111/animations/enzyme.html • Catalase in an example of an enzyme made by living cells www.assignmentpoint.com

  4. Catalase • The enzyme catalase breaks down the waste substance hydrogen peroxide into water and oxygen. catalase Hydrogen peroxide oxygen +water (enzyme) (substrate) (products) www.assignmentpoint.com

  5. Degradation reactions animation www.assignmentpoint.com

  6. Synthesis Reaction es Active site www.assignmentpoint.com

  7. Degradation reactions Starch Maltose www.assignmentpoint.com

  8. Enzyme activity Temperature and pH affect the activity of an enzyme. www.assignmentpoint.com

  9. Optimum Condition Enzymes function best or are most active in specific conditions known as optimum conditions. www.assignmentpoint.com

  10. Degradation reaction www.assignmentpoint.com

  11. Synthesis reaction Glucose-1-phosphate Starch www.assignmentpoint.com

  12. Properties of enzymes Speed up reactions. Made of protein. Are specific. Not used up during the reaction. Require optimum conditions at which they work best. At high temperature they become denatured www.assignmentpoint.com
