Presentation Transcript

  1. AP Biology Cellular Respiration Part 1

  2. Electron Transport chain creating a concentration gradient in a Thylakoid

  3. Redox reaction

  4. Light energy ECOSYSTEM Energy Coupling between Photosynthesis and Cellular Respiration Photosynthesis in chloroplasts Organic molecules CO2 + H2O + O2 Cellular respiration in mitochondria ATP powers most cellular work Heat energy

  5. Cellular Energy

  6. Is Oxygen present?

  7. Photosynthesis and Cellular Respiration chemical reactions(Remember… conservation of matter.) 6 CO2 + 6 H2O  C6H12O6 + 6 O2 + Heat Photosynthesis C6H12O6 + 6O2  6CO2 + 6H2O + Heat + Free E Cellular Respiration

  8. ATP Structure

  9. Phosphorylation using Free energy

  10. Redox reaction

  11. Valence is important with electronegativity

  12. Series of Redox reaction(Electron Transport chain)

  13. “Making” of electron carriers • NAD⁺ +2 electrons + H⁺ ion = NADH • FAD⁺ + 2 electrons + 2 H⁺ ions = FADH₂

  14. Electron Transport Chain is ALWAYS located on a membrane

  15. Oxygen is at the end

  16. Process of Cellular Respiration

  17. Energy Investment Phase &Phosphofructokinase

  18. Energy Payoff Phase
