Hardcore biochemistry!

Wish I'd applied for biochemistry now. For off-spec it's all about ribozymes though.

RNA molecules that catalyse reactions like enzymes :eek:

Well in order to write a good essay I'm concentrating on a few essays because there is just too much content too remember.

ATP and Proteins have not come up for a long time so I hope they come up.
Also just going through variation. Doubt enzymes will come up as it was in the June 2008 paper.

So you dont think the last four questions could up then? I think as theres only been two papers of this spec its two early for them to repeat. But they would probrably bring in anything from the old spec so enzymes could may well come up again.

My essays ''plans'' atm only consist of looking at what content mark schemes say should be in a particular essay. A lot of essay questions seem to me to be about the same ''topic'' - just worded differently. So alot of the things that are in the mark scheme for question will probrably be in the mark scheme for another question provided both questions are on the same ''topic'' (give or take a few things) I've just looked through mark schemes to see which topics to learn :smile:

ATP -
characteristics/stucture of ATP (like soluble, immediate energy source etc.)
production in ETS in respiration
production and use in photosynthesis in glycolysis
production in anaerobic respiration

This is all i can think of and its all mainly biol4 stuff :s-smilie:

Proteins -
structure (tertiary structure, amino acids etc.) peptide bonds
transfer proteins - protein channels, facilitated diffusion, carrier proteins
protein synthesis - transcription, translation, polypeptide chains

Sorry they are quite basic, :frown:

someone posted this link earlier:

which has more detailed essay plans!

EDIT --
I also missed loads of college at the end of term and ended up having to try and teach myself gene technology stuff!

I've revised well for unit 5, and I'm sure I'll be okay if there's an essay on that, but seriously, how do you all manage to remember things so well from old units? :frown:

I can write like a few sentences on any topic, but not really in-depth detail, let alone information from beyond the syllabus. :frown:

What ways are you guys using to help you revise the old stuff? I'm really worried that I'll go blank as soon as I see the essay questions. :s-smilie:
