Presentation Transcript

    1. 1 Enzymes

    2. 2 What Are Enzymes? Most enzymes are Proteins (tertiary and quaternary structures) Act as Catalyst to accelerates a reaction Not permanently changed in the process

    3. 3 Enzymes Are specific for what they will catalyze Are Reusable End in ase -Sucrase -Lactase -Maltase

    4. 4 How do enzymes Work? Enzymes work by weakening bonds which lowers activation energy

    5. 5

    6. 6 Enzymes

    7. 7

    8. 8 Enzyme-Substrate Complex The substance (reactant) an enzyme acts on is the substrate

    9. 9 Active Site A restricted region of an enzyme molecule which binds to the substrate.

    11. ENZYME ACTION http://highered.mcgraw-hill.com/sites/0072495855/student_view0/chapter2/animation__how_enzymes_work.html

    12. Enzyme Substrate Complex (Induced Fit)

    13. 13 1. Environmental Conditions 1. Extreme Temperature are the most dangerous - high temps may denature (unfold) the enzyme. 2. pH (most like 6 - 8 pH near neutral) 3. Ionic concentration (salt ions)

    14. 14 2. Cofactors and Coenzymes Inorganic substances (zinc, iron) and vitamins (respectively) are sometimes need for proper enzymatic activity. Example: Iron must be present in the quaternary structure - hemoglobin in order for it to pick up oxygen.
