Summary ELECTRON TRANSPORTATION

Electron transport chain
&
Oxidative Phosphorylation

, Electron transport chain
 Reducing equivalent are generated during aerobic catabolism of glucose as well as proteins and fat.

 These include: NADH and FADH2

 For complete glucose oxidation to CO2




?
 Aerobic degradation of carbohydrate, lipid and amino acid converge at the electron transfer to O2

, Electron transport chain
 By product of glucose oxidation




 Electron generated are NOT transfer directly to O2 BUT rather via to coenzymes i.e.

 NAD+ forming NADH

 FAD forming FADH2

, Electron transport chain
 Generation of the reducing coenzymes i.e.
 NAD+ and NADH

 FADH2 from FAD
