Electron Transport Chain.

There's a special protein called-- and I'll show you actually a better diagram of what looks like in a second-- called ATP synthase. And what happens is, remember because of the electron transport chain, we have all of these hydrogen ions up here, all of these protons really.

Either one of those is the case. Now this is really the first step of the electron transport chain. These electrons are transported out of the NADH. Now, the last step of the electron transport chain is you have two electrons-- and you could view it as the same two electrons if you like-- two electrons plus two hydrogen protons.

The chemiosmotic theory explains the functioning of electron transport chains. According to this theory, the transfer of electrons down an electron transport system through a series of oxidation-reduction reactions releases energy (Figure 18.3 D. 1 ). This energy allows certain carriers in the chain to transport hydrogen ions (H + or protons ...
