Presentation Transcript

  1. Section 3B – Macromolecules (Proteins) Part 4: Enzymes (Part 3)

  2. Part 4: Enzymes Enzyme activity can be affected by various factors

  3. Part 4: Enzymes Objectives: Describe how different conditions impact enzyme function

  4. Part 4: Enzymes Enzymes, Optimal Conditions, and Substrate Concentrations An enzyme functions best at an optimal temperature and pH

  5. Part 4: Enzymes Enzymes, Optimal Conditions, and Substrate Concentrations Reaction rate slows if enzyme is placed in less-than-optimal conditions

  6. Part 4: Enzymes Enzymes, Optimal Conditions, and Substrate Concentrations When conditions disrupt enzyme structure, enzyme activity is affected

  7. Part 4: Enzymes Enzymes, Optimal Conditions, and Substrate Concentrations Temperature and pH too high or too low can cause an enzyme to denature and stop working

  8. Part 4: Enzymes Enzymes, Optimal Conditions, and Substrate Concentrations

  9. Part 4: Enzymes Enzymes, Optimal Conditions, and Substrate Concentrations Different enzymes function best in different conditions

  10. Part 4: Enzymes Enzymes, Optimal Conditions, and Substrate Concentrations Acidophilic bacteria

  11. Part 4: Enzymes Enzymes, Optimal Conditions, and Substrate Concentrations Thermophilic bacteria

  12. Part 4: Enzymes Enzymes, Optimal Conditions, and Substrate Concentrations Determine optimal temp and pH of the enzyme below. Would this enzyme exist in the body?

  13. Part 4: Enzymes Enzymes, Optimal Conditions, and Substrate Concentrations Increasing substrate concentration for an enzyme results in more product

  14. Part 4: Enzymes Enzymes, Optimal Conditions, and Substrate Concentrations Enzyme activity eventually levels off product produced substrate concentration

  15. Part 4: Enzymes Enzymes, Optimal Conditions, and Substrate Concentrations Active sites of all enzymes are filled, so excess substrates will not be catalyzed

  16. Part 4: Enzymes Enzymes, Optimal Conditions, and Substrate Concentrations Increasing enzyme concentration results in more product

  17. Part 4: Enzymes Enzymes, Optimal Conditions, and Substrate Concentrations Enzyme activity eventually levels off product produced enzyme concentration

  18. Part 4: Enzymes Enzymes, Optimal Conditions, and Substrate Concentrations All substrate molecules are bound to enzymes, so excess enzymes have no substrates

  19. Part 4: Enzymes Additional Reading Read pg 52-53 Complete Homework 3B-2
