    Ive got 2 books that im studying from, one is the aqa one, the other is oxbox.

    When talking about the electron transport chain during respiration, they both are different.

    AQA one: electron from the hydrogen atom accepted by the first molecule of electron transport chain, moves down to lower energy electron carrier molecules, releasing energy as it goes down which is used to synthesis ATP from ADP+Pi. The protons simply accumulate in the space between the inner and outer membranes then diffuse back into mitochondrial matrix through special protein channels.

    OXBOX one: electron from the hydrogen atom accepted by the first molecule of electron transport chain, moves down to lower energy electron carrier molecules, releasing energy as it goes down which is used to pump protons from mitochondrial matrix to the space between the inner and outer membranes. This creates a steep concentration gradient. The inner mitochondrial membrane is impermeable to protons except at special structures called stalked particles that function as chemiosmotic channels. The energy associated with the diffusion of the protons back into the mitochondrial matrix through the chemiosmotic channels of stalked particles drive the synthesis of ATP.


    Which of these have you been taught and which would u advise to learn?

    We only ever use the AQA book so personally, I'd go from that. It's not like they'd want so much detail for an answer in the exam but not put all of the information in their own book, right? D: I hope not anyway, that book is all I've been going from.

    The red answer is more correct, but it's safer to stick with your exam board explanation for the purposes of exams. Not a bad idea to have a more detailed view of how it works if you're aiming to take science (that'll include this obviously) forward though ...

    AQA Book. Despite being pretty damn ridiculous, it has everything you need in it and hasnt missed out important material.

    They're both essentially the same thing.

    The OXBOX version is just more specific, and thus you should go with that one.

    No, because an AQA mark scheme won't necessarily include those marks of more detail.

    For exam passing purposes, stick to your exam board. For education purposes, read around the subject.
