AQA BIOL1 Biology Unit 1 Exam - 16th May 2011

What was the best pH? I put 9 because it had the smallest diameter so had the most removed (question said that protease removed it) so was the most effective.

oh ok so i basically wrote that, what was the wording of the last question?

cos i didnt seep adapted i jut read how is glucose absorbed into the blood so i basically explained the whole process about co trasnport atp conc gradients na/k pump, faciltated diffusion all that, i didnt even right about microvilli ?:s

That wasn't a question was it? I thought it was about optimum?

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

I put the one with the largest diameter, was it not protease in the little circles, and the diameter around them how much of the plate thingy the protease digested?

The question was about describing the trend I think. Said as pH increased rate increased.

Yes I talked about surface area too
I also said that the thickness of exchange surface was very thin. Not sure it that is correct though..

I also put this.. It seemed too simple!

Yeah but heard of Occam razor?

i thought the rate decreased with increased ph cos the circles got smaller

What did people write for the question involving Phagocytosis and how it destroyed bacteria?

Yepp
Lets hope then!
