ATP

  1. 1. Structure and Function of ATP
  2. 2. What is ATP? <ul><li>ATP is the cell’s source of energy. </li></ul><ul><li>It is used by almost all biological reactions that occur in your body. </li></ul>
  3. 3. Structure <ul><li>3 Parts: </li></ul><ul><ul><li>Adenosine (nitrogenous base) </li></ul></ul><ul><ul><li>Ribose (sugar) </li></ul></ul><ul><ul><li>Three Phosphates </li></ul></ul>
  4. 4. Source of Energy <ul><li>During chemical reactions ATP gets broken down into ADP (Adenosine Di-Phosphate). </li></ul><ul><li>The bond that holds the last phosphate group is broken. </li></ul><ul><li>When this bond is broken energy is released. </li></ul>
  5. 5. ADP - ATP <ul><li>Energy is then needed to re-create the bond and form ATP </li></ul>
  6. 6. ATP Cycle
  7. 7. ATP Cycle
  8. 8. Summary Questions <ul><li>What is the biological importance of ATP? </li></ul><ul><li>When ATP is broken down, what is it converted into? </li></ul><ul><li>Where do we get the energy to make ATP from? </li></ul>
