ELECTRON TRANSPORT CHAIN

Also known as respiratory chain, it is located in the inner mitochondrial membrane.. 

• Coenzyme Q & Cytochrome C are mobile components. 

The reactions start by removal of Hydrogen (H+ and one electron) from the substrate that is transferred through different components of Electron Transport Chain in accordance of “Increasing Redox Potential” to oxygen to form water.

• Components of ETC are Complex I, II, III, IV & V which are membrane bound components. 

• Complex I to IV each contain part of the electron transport chain. 

• Complex V catalyzes ATP synthesis
