Electron Transport + Oxidative Phosphorylation
Produces a lot of ATP |
Energy carried by electrons from reduced coEnzymes is used to make ATP |
CoEnzymes NAD.2H and FAD.2H |
Previous stages have been used to make NAD and FAD |
Location
Takes place in the Inner mitochondrial membrane |
Overall Reaction
NAD.2H + 1/2 O2 + ADP+Pi = NAD + H2O + ATP |
|
|
Oxidative Phosphorylation
Energy carried by Electrons from reduced CoEnzymes make ATP |
Involves Electron Transport Chain and Chemiosmosis |
Steps of Oxidative Phosphorylation
Hydrogen Atoms released from Reduced NAD.2H and FAD.2H |
Oxidised back to NAD and FAD |
H atom splits into Protons and Electrons |
Electrons move down the ETC losing energy as they go |
Energy is used to pump Protons from Mitochondrial Matrix into Intermembrane Space |
Results in a Concentration of Protons form a Electrochemical Gradient |
Protons move down electrochemical gradient via ATP synthase back into the Mitochondrial matrix |
This drives the synthesis of ATP from ADP and Pi |
ATP production driven by the movement of H+ ions across membrane is called Chemiosmosis |
