I put cytoplasm for W.. Unsure tho.. Got the same as your other ones tho

it was the sucrose solution, because the plasma membrane had pulled away from the cell wall because all the water had left the cell. (plasmolysis) As the cell wall is freely permeable the solution could flow through it but could not pass the membrane.

will Bohr shift give me the mark or was it meant to be Bohr effect?

Bohr shift seems fine, i put that too

the first one was C because it was asking for proof that it is an active process and this one mentioned drugs that inhibit respiration.then the second was ADF or something like that cant remember.

I got these too, fairly sure the active one could only be C as none of the others showed that it was active, and it makes sense to get 3 for the other one as it was 4 marks in total.

It was sucrose/assimilates as the cell wall is fully permeable.

I think the grade boundaries will be in the middle like 75% for an A cos some found it hard and some found it easy it's a mixture and it's a new spec do more likely to be lower. I found it in the middle tbh I made some stupid mistakes lol. I hope I get a least a C and an a on depth so I can get a B overall, fingers crossed

So many people being blatant wind ups. That was not an easy test at all. Major parts of the spec were skimmed over. Many questions were so specific and took guess work. I've been creating in depth revision cards on every module throughout the year. I haven't had a social life. That exam was the most disappointing I've ever taken. All of my others I'm pretty sure I'l get an A/B on. To anyone else reading this and thinking that they're the only ones who found that really hard, you're not. To those who thought it went really well for them, I'm happy for you :3 .

its water. without sucrose as it cant pass the cell wall, but water can

Come on, there's no way that paper was in the league of the specimen paper's, which is what we were expecting, so its a nice break at least. It is similar difficulty to legacy papers, so a grade boundary for A around 55 seems appropriate given no longer answer qustions

I feel like a lot of people made silly mistakes which can add to make a lot of marks gone. Maybe because of that the grade boundaries will be lower?
