The carbons are oxidised to Carbon dioxide in Krebs Cycle. And making bonds = energy given off. Where as in the Oxidative phosphorylation, energy is released when electron from the carriers (NADH) move down the electron transport chain, through the stalked particles and join with acceptors such as oxygen. (This is how water's formed during respiration. The process seemed so much simpler during my GCSE year. Sigh)

:: Afifa ::, you could give history and geography a try. Though you'll have to be writing a whole load of essays in a very short time.

are you saying an example of an electron carrier is NADH? I thought it was cytochrome.

What board are you with for Biology?

No they're hydrogen carriers. It's just that the electrons are with the hydrogen when the hydrogen is carried. My wording was imperfect.

EDIT: (Now that I've read the post again, I relised it's not my bad. My wording was fine. You're interpretation was wrong. So I removed the 'my bad' from my post).

R.E. has essays too. You might want to consider Economics. Not many sixth forms/colleges offer it though.

About history, I think it's a lot to do with essays. But obviously you'd need to know the dates, the incidents, the people etc. You would also need to be able to understand complicated sources. Or so I've been told by my friend who does A-level history.

cool...Sounds good...(Well I say that because I like it.):p
 
I did AS level History, and yes it is quite a lot of writing. You need to develop your analytical writing in particular. What may have been an A* grade essay at GCSE may only be a C grade at A-Level. It's a lot more in depth.

U can do subjects like this if ur good at written english
