Transcript

  • 1. What is the role of an enzyme in a chemical reaction?
  • 2. <ul><li>What happens to ice when you leave it on the counter? </li></ul><ul><li>How could you speed up the process of ice melting? </li></ul><ul><li>As you think about those answers, Click here to watch a short clip regarding enzymes. </li></ul>
  • 3. <ul><li>Chemical Reactions change substances into new substances. </li></ul>Reactants Products
  • 4. <ul><li>Activation Energy: the amount of energy needed to start a chemical reaction </li></ul><ul><li>like the amount of energy needed to push the rock to the top of the hill. </li></ul>
  • 5. <ul><li>the guy in the previous picture has to apply energy to the rock to get it to the top of the hill. </li></ul><ul><li>once it’s there, the rock can move down the hill on its own </li></ul><ul><li>the enzyme pushes the reaction (by providing a bit of energy) to a point where it can continue on its own </li></ul>
  • 6. <ul><li>How much activation energy was needed to melt the ice cube (a lot or a little)? </li></ul><ul><li>How could we change the amount of activation energy needed? </li></ul><ul><ul><li>by applying heat from a hair dryer to the ice cube </li></ul></ul><ul><ul><li>by rubbing it between your hands </li></ul></ul><ul><ul><li>by putting it directly in the sun </li></ul></ul>
  • 7. <ul><li>Enzymes (specialized proteins in our bodies) LOWER the activation energy of specific reactions. </li></ul><ul><ul><li>It takes less energy to get things started </li></ul></ul><ul><li>Therefore ENZYMES make it easier for chemical reactions to occur in our bodies. </li></ul><ul><li>They also make the reaction happen faster. </li></ul>
  • 8. <ul><li>By using an enzyme, you essentially make the hill shorter. </li></ul><ul><li>What point (A, B, C, or D) shows the point after an enzyme reduced the activation energy for the reaction? </li></ul>
  • 9. <ul><li>When an enzyme is involved, reactions can happen much faster. </li></ul>
  • 10. <ul><li>Each enzyme can only go with one reaction. This depends on the shape of the active site. </li></ul><ul><li>Similar to how one specific key fits into one specific lock. </li></ul>
