The questions were far too applied. The paper 1 last year was so much easier and I found it to have a lot more content that was actually important to the specification. If AQA don't sort themselves out they are going to be seriously reprimanded because the papers this year (both GCSE and A-level) have been shocking according to students reviews and they need to sort themselves out otherwise I am sure that people schools are going to switch their exam boards to edexcel or OCR where the papers are more fair!!

I would totally agree. It was as if AQA were trying to make you spend ages on the first half of the paper so that you didn't have enough time to answer the longer questions at the end which is cruel. Although, I didn't fall in that trap as I straight away went to the back because I know what AQA are like!

it was a competitive inhibitor, cause it binded to the active site reduced e-s complexes

Competitive inhibitors bind to active site, Cyclin A “binds to the protein to be used in dna replication” so it must have been alosteric

I put prophase, couldnt see movement but was doubled and visible?

What reason for the difference in Fe3+ did you suggest between the old and young leaf? So confused on that question - described results - not much else....

I said it was prophase because they hadn't alligned at the metaphase plate.

For the potato one did you get the surface area of the 1 cube to be 35x35x6=7350 and then the total surface area of the 8 tubes to be 17.5x17.5x6x8=14700? And then I didvided each by 62g for mm2 per g, and then timed by the gradients which were -0.225 and -0.125 to get the rate of osmosis being -26.7 mm2 per minute for the large cube and for the 8 small cubes -29.6

I need to lie down.

I said Anaphase too, then changed it to prophase, then changed it back to anaphase. But hey it was only a mark :smile:
