Electron Trannsport Chain and ATP Synthesis

This video helps with understanding the mechanisms involved and what is meant by the movement of electrons. In this video the electron transport chain is said to have 3 protein complexes and one other protein complex that carries out ATP synthesis. This is only partially accurate.

The 3 complexes seen in this video are the only three complexes that pump protons into the intermembrane as seen in the diagram bellow.

There are 4 protein complexes that make up the electron transport chain. They are:

Complex I : NADH Dehydrogenase

Complex II : Succinate Dehydrogenase

Complex III : Cytochrome b-c1

Complex IV : Cytochrome Oxidase

This together with Complex V : ATP Synthase

carry out aerobic respiration as seen in the diagram bellow

The next video shows the production of ATP via the concentration gradient created by the electron transport chain.
