im so pissed at myself i didnt see the ADAPTED part of the last question so all i wrote was:

sodium potassium pump, active transport, atp, diffusino gradients, co transport, facillated diffusion all the stuff.
IS THAT NO MARKS?

I thought it said how is glucose absorbed not how is cell adapted for absorption?

I think thats right |:
urgh im pissed off...... wrote too much about villi which won't be credited apparently.

Cambridge have a special access scheme and you sound like a perfect candidate.

Why won't it be credited? Isn't having villi/microvilli to increase s/a an adaption? :s-smilie:

i didnt mention sodium potasium pump or carrier proteins

i swer it sed adaptations of epitalil cells in small intestine, i spoke about vili which it hink is differnt but i put like diffsuino conc gradient, large sA?

i swear epithelial cells is different from villi

That what im saying, i misread the question and didnt put ANY adaptions, literally just explained the uptake of glucose using all those terms. Do you think i'll get any marks at all?

IF NOT GOODBYE 100 UMS

Yeah, Individual epithelial cells have microvilli

just to calrify the answer is epithelial cells have vill/microvilli which is adapted by hvin diffusion distance less, lartge sa etc..........

Please can somebody tell me all the stuff for the villi was wrong so i can r.i.p?

no its right, its got nothing to do wid sodium potasium pump or carrier, they sed how it is ADAPTED and epithelial cells have microvilli which icreases SA

first 1 i didnt mention but many mitochondra for atp
short diffusion distance
large sa
blood vessels manitiang conc gradeiennt
other stuff lol

maybe carrier protiens

**** that means ive lost 6 marks completely straight there becuase i didnt realise it said adapted so didnt talk about any of that stuff at all. OMFG
I NEED AN A IN IT!

Don't worry you still got extra, and clearing and...

Well i guess you're screwed.

Just joking, I'm probably more screwed considering I haven't revised a single minute for any of my exams.
