does anyone have a good clear bulletpoint style description for the Electron Transfer Chain and Oxidative Phosphorylation???
Ive got clear notes on Glycolysis, Link Reaction, adn Krebs Cycle but im stuck on this.
any help would be great, thanks!

OK... is only a very basic one on what i remember from unit 4 though
NADH is oxidised to NAD
Electrons pass down a series of cytochromes
Last electron acceptor in the chain is oxygen
Reduced to water
ADP passes through the mitochondrial membrane by energy produced as electron passes down series of cytochromoes
ADP enters stalked particles
Stalked particles contain ATPase
ATPase converts ADP into ATP
(I'd advise you to check your syllabus / notes cuz it maybe different for a different board)

Edexcel prefer you to say that the redox reactions that occur as electrons are transferred along the electron acceptors on the inner mitochondrial membrane causes H+ ions to move out of the matrix and into the intermembranal space. As the H+ ions flow back through the stalked particles (arent these the cytochromes?!), the energy released is used to convert ADP + Pi -> ATP, by the action of ATPase.

The cytochromes are the electron carriers. The stalked particles are part of the H+ ion protein channels, and act as ATP synthases.
