    hey all

    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.

Will you be tempted to trade up and get out of your firm offer on results day?
