  7. Chapter 9Cellular Respiration Many reactions involve the transfer of an electron from one atom to another.

  8. Chapter 9Cellular Respiration Many reactions involve the transfer of an electron from one atom to another. Na Cl

  9. Chapter 9Cellular Respiration Many reactions involve the transfer of an electron from one atom to another. Na Cl

  10. Chapter 9Cellular Respiration Many reactions involve the transfer of an electron from one atom to another. Na Cl

  11. Chapter 9Cellular Respiration This moves an electron from a high energy (unstable) configuration to a low energy (stable) configuration. Na Cl

  12. Chapter 9Cellular Respiration We can tap the energy that is released by this electron. Na Cl

  13. Chapter 9Cellular Respiration We can tap the energy that is released by this electron. Na Cl

  14. Chapter 9Cellular Respiration We can tap the energy that is released by this electron. Na Cl

  15. Chapter 9Cellular Respiration We say chlorine is “reduced” because its charge (it’s “oxidation number”) goes down. Na Cl

  16. Chapter 9Cellular Respiration We say sodium is “oxidized” because oxygen is the most common oxidizing agent. Na Cl

  17. Redox

  18. Redox Ger…

  19. Redox Ger… Leo says “Ger”

  20. Redox Ger… L E O G E R

  21. Redox Ger… Loss of Electrons is Oxidation G E R

  22. Redox Ger… Loss of Electrons is Oxidation Gain of Electrons is Reduction
