RuBP accepts 1 carbon from Co2 in order to create 2xGP, without GP the rest of LIR cannot continue

Hopefully, I’m relying on my knowledge in this paper as application questions are horrible!

i predicted the immunity and ELISA tests right :smile:

for paper 2:
- topic 8! pretty much all of it. there wasn't much on it in 2022 paper and it's something they'll want to test on
- control of blood glucose concentration & control of water potential (kidneys)
- muscles
- succession and epistasis
- less of a focus on topic 5 since there was a lot in 2022, but there will still b qu's on it!

the way u saved my life for paper one absolute legend, agreed on the topic 6 stuff and im glad topic 5 was heavy last year hopefully there isnt too much on it! topic 8 is my enemy though, dna tech is so evil, if i see human genome project tears will form..

i think it will be but we shouldn't put all our eggs in one basket, paper one was a lot more application heavy than previous years so im hoping there is a few 3/4 markers on knowledge and AO1 (and please less graphs AQA im begging) but yeah

tbh its likely to be, im going over muscles now cause i dont get any of it, i would really recommend you go over it if youre not too confident at least we still have a week!
