1. Lecture 9
Respiration

2. Oxidation-Reduction Reactions
Cu(s) + 2 Ag+(aq) → Cu2+(aq) + 2 Ag(s)
Cu → Cu2+ + 2e-
2 Ag+ + 2e- → 2 Ag

3. Oxidation- Reduction in Respiration
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy
reduction

4. Nicotinamide adenine dinucleotide – the electron acceptor

5. The slow release of energy

6. Glycolysis

7. glucose 6-phosphate
ATP, citrate

8. Moving to the citric acid cycle
