Respiration Summary By Luke Runacres

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

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

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

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

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
