I'm afraid talking about villi will get you nothing, as that is not how the CELL is specialised, but how the intestine is specialised. Otherwise that sounds like a 4/5 out of 6 answer.
Wasn't it about epithelial cells in the small intestine lumen?

If they are not there to catch you out why do they ask such vague questions then have such precise mark schemes? Why do they not bother to mark the exam papers properly? Why is it that for the same question on different papers you need different answers? They are SUPPOSE to differentiate but they do a **** job.
Because by asking vague questions they are differentiating! It's all about applying the knowledge you have :P I'm sure you will do fine though <3

for the atheroma guys, u say faty deposits in wallf of atery culd lead to thrombosis, so reduced supply of o2 reaching heart, less repsiration or atp provided so heart attack lol
The high blood pressure can dislodge the arethroma or cause damage to other arteries. If it gets dislodged it can clot the coronary arteries.

isit allright to talk about carrier proteins and protein channel for the 6 mark question
That's what the majority of people seem to have talked about
I uncluded carrier proteins and channel proteins too

You differentiate by asking questions which are specific and have specific answer. AQA do a **** job at it, there is not debating that.

Thanks. You too, good luck we all need it.

thats probz fine, but it asked how epithelial cells are ADAPTED to lining intestine, now if u went to the book it has the exact rasons like many microvilli to increase sa

Did anyone else get a booklet without those "additional sheet" things, ot atleast extra pages for writing.

Because I was like writing alot of crap on the last question and ran out of space, turned the page and was like wtf when I saw there was no additional space. Had to get lined paper from the office and staple it to my booklet.

i believe the question went something like...

how are the epithelial cells of the small intestine specialised for the absorption of glucose?

i wrote about how it narrows the atery due to cholesterol/fatty deposit. but then i talked about thrombosis and anurisms... i think this is wrong.
i think it may be ok as long as you linked it back to causing heart attack because thrombosis can cause heart attacks too

Not sure but I think there were a few, I was wondering why there were so many 1 markers anyway.

The one about describing how they got per 100,000 was one.

Just researched it. Apparently the whole test was not related to the sylubus. Wonder what happened :/
The people who created the exam were on a acid trip.

They won't be that high. Previous years had that amount for 100 UMS
Probably 43 max.
