Edexcel GCE Biology Unit 1 (Old specification) [25th May 2017]

Haven't seen a thread for this exam, probably due to not many people doing it as its a resit only paper, so decided to create one.

This thread is for post and pre exam discussion, so free feel to make predictions, ask questions about the exam etc..

I found it hard, the questions were set out very differently from past papers, wbu?

There were a few from past paper questions. I ran out of time at the end, but overall not bad. We'll see on results day yikes! Are you doing any other biology modules?
It was okay but very open ended, quite different from past papers and made a few mistakes/almost ran out of time.

Can we discuss answers?

Can anyone remember the questions?

Honestly, it was different from past papers. There was a lot of application! I remember there was a question on energy balance, dialysis (heavy application), mutations, amino acids (what did people do for the diagram I got stumped on that one). I answered all the questions but I didn't like the paper at all

Just drew the basic amino acid with the the suggested r group no?

What did people write for the treatment of CVD that would help the smoker? I put ACE inhibitors but I'm not sure.

There were a few nice easy questions but it didnt make up for the fact it was quite a nasty paper. I thought it would be easier considering not many people would be retaking it but I guess I thought wrong lol

There was one question on protein synthesis where i explained translations and transcription. I also remember talking about protein structure and how it changes like primary>secondary>tertiary in terrms of folding and bonds. For the amino acid one i replaced the R group with the ch2-ch2-cooh groups and normally drew an amino acid so central carbon with nh2 and cooh group :smile:

I put statins and explained what it did lol i regret that now. i also forgot to mention how BP decreases too but i think any drug should be fine within reason of explanation

So did you guys keep the amine and carboxyl then what did you add in place of the r group, CH2? I got a bit confused because it had CH2-CH2- and I wasnt sure why there was two?

Anyone say antihypertensives???

the r group was ch2-ch2-cooh

Which diagram??

the one with the amino acid but I feel dumb now I realise I was getting confused for no reason aha !
