  1. Education Pays

  2. What do you want to be when you grow up? • Many possibilities to use your biological education. • Biologist • Life Scientist • Doctor/Nurse • BioEngineer • Chemical Engineer YOUR DECISION HAS $$$ CONSEQUENCES!

  3. Job Growth • Growth rate is ~35%/yr

  4. Salary Information • Median Salary for B.S. =$35k/yr • Starting Salary ~$24/yr-$30k/yr

  5. CatalaseThe Enzyme

  6. Using Enzymes in Industry

  7. Catalase • Liver Enzyme • Reaction • decomposition of peroxide • 2 H2O2 ----> 2 H2O + O2(g) • Catalase acts as a catalyst • increases the rate of reaction

  8. Rate Plot

  9. Catalase Enzyme

  10. Catalase - Tetramer

  11. Catalase Active Site Heam Site

  12. Catalase Mechanism • 2 H2O2 <----> 2 H2O + O2(g)

  13. Catalase Mechanism

  14. k1 Fast!! k2 Slow • k1 = Enzyme-Substrate Association • k1 Runs at 4x the Speed Limit, • Diffusion Limit • k1 = 4 x 108 Liter/(mole sec) • k2 = Product Kickout from Active Site • Much Slower than the Speed Limit • Speed limit 1010 1/sec • k2 ~10 1/sec

  15. Rate Plot
