1. AP Biology Cellular Respiration Part 1

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

3. Redox reaction

4. Energy Coupling between Photosynthesis and Cellular Respiration ECOSYSTEM Light energy Photosynthesis in chloroplasts Cellular respiration in mitochondria Organic molecules + O 2 CO 2 + H 2 O 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
