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 is ALWAYS located on a membrane

15. Oxygen is at the end

16. Process of Cellular Respiration
