How did you all find it? :smile:

Thought it was an alright paper!
The respiration/photosynthesis was a bit hard.

I thought it was alright too but I didn't like the experiment question.
I wrote some really stupid things for that.
Loved the rest though!

What did you write for the very first 6 mark question about negative feedback controlling glucose concentrations?

I wrote the whole story lol.
Everything about insulin and glycogen.

How did you manage that in the space given?
I just wrote about insuling
Increase in Blood Glucose Levels, More Atp made in beta cells, trigger release of Insulin, Blood glucose goes down, Less insulin secreted - thats the jist of my answer for that question

What did people put for the outer structure of the chloroplast, do you think they will allow outer membrane?

Also what did guys put for the calculation question and the microscopic picture where it had the glomerulus and you had to identify the structures?

Also what did you guys put for the calculation question on respiration, did u divide the volume by 60 and what did people put for the structures in the microscopic picture when they said one of them is the glomerulus.

hi tamuno

i got outer membrane for the choloroplst

i wantd to know the rate of rspiration increases with temperature.

wat did u put for that

so was I the only one who thought it was a disaster? omg, hate life

For the respiration increases with temperature, I talked about an increase in kinetic energy, how the movement of hydrogen ions and chemiosmosis increase so ATP can be produced quickly. What did you put?

FINALLY OCR HAS GIVEN US A NICE PAPER! :biggrin:

the only questions that i wasn't sure about were the type 2 diabetes question, the respirometer, i didnt know what the stimulus for smell and taste was, but now i know ><" oh and i completely forgot about the chloroplast envelope, i knew it wasn't the cell wall but i couldn't think of the word! so i put cell surface membrane even though i knew it was wrong :frown:

so i've lost a few marks, but it wasn't too bad :smile:

i hope i still get an A.

For the calculation question did u guys do the volume/60s

Anyone..?

Anyone..?

Answer was 0.014 :smile:

I divided by 20!

The exam was only yesterday and I've already forgotten everything about it lol. Its what a chemistry exam does to you.
For the calculation question I remember dividing the difference by 20.
For the kidney diagram question I wrote collecting duct but I know its wrong. Its supposed to proximal convoluted tubule or distal, I've been told.

Glass Beads? We've never been taught anything really about anything that question was about!
I didn't know the stimuli for nose or tongue either.
It was a very... weird paper.
