1 Education Pays

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

3 Job Growth n Growth rate is ~35%/yr

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

5 Catalase The Enzyme

6 Using Enzymes in Industry

7 Catalase n Liver Enzyme n Reaction u decomposition of peroxide n 2 H 2 O 2 ----> 2 H 2 O + O 2 (g) n Catalase acts as a catalyst u increases the rate of reaction

8 Rate Plot

9 Catalase Enzyme

10 Catalase - Tetramer

11 Catalase Active Site Heam Site

12 Catalase Mechanism n 2 H 2 O 2 2 H 2 O + O 2 (g)

13 Catalase Mechanism

14 k 1 Fast!! k 2 Slow n k 1 = Enzyme-Substrate Association n k 1 Runs at 4x the Speed Limit, u Diffusion Limit F k1 = 4 x 10 8 Liter/(mole sec) n k 2 = Product Kickout from Active Site u Much Slower than the Speed Limit u Speed limit 10 10 1/sec F k 2 ~10 1/sec

15 Rate Plot

16 Hayes’ Data
