1. Respiration Summary By Luke Runacres

2. 4 Stages Glycolysis – Cytoplasm Link reaction - Matrix Krebs Cycle - Matrix Electron transport chain – Inner membrane

3. Glycolysis Glucose Hexose-6-phospate Hexose-1,6-bisphosphate 2 x Triose phosphates Intermediate Pyruvate ATP  ADP+Pi ADP+Pi  ATP NAD  Reduced NAD

4. Anaerobic Respiration PyruvateLactate NAD Reduced NAD Fermentation PyruvateEthanalEthanol NAD CO 2 Reduced NAD Only 2 ATP! Anaerobic Respiration

5. Link Reaction Prepares the pyruvate for the Krebs cycle… PyruvateIntermediateAcetyl CoA CoA CO 2 Reduced NAD

6. Krebs Cycle Citrate (6C) 5C Intermediate 4C Intermediate Oxaloacetate (4C) Acetyl CoA (2C) CoA CO 2 NAD Reduced NAD ADP+Pi ATP NAD Reduced NAD NAD Reduced NAD FAD Reduced FAD

7. Electron transport chain H+H+ H+H+ H+H+ H+H+ H+H+ H+H+ H+H+ H+H+ H+H+ 3ADP+3Pi  3ATP Reduced NAD  2e - + 2H + + NAD 2e - 2H + + 2e - + ½O 2  H 2 0 H+H+ H+H+ H+H+ H+H+ H+H+ H+H+ H+H+ H+H+ H+H+

8. Electron transport chain H+H+ H+H+ H+H+ H+H+ H+H+ H+H+ H+H+ H+H+ H+H+ 2ADP+2Pi  2ATP Reduced FAD  2e - + 2H + + FAD 2e - 2H + + 2e - + ½O 2  H 2 0 H+H+ H+H+ H+H+ H+H+ H+H+ H+H+ H+H+ H+H+ H+H+
