Maybe you guys are right. the molecule was sticking out, it was just the hexagons that put me off.. confusing.

Which is why I think that cholesterol is the better answer, because it doesn't have to be attached to a protein molecule in the membrane.
Yeah we're talking about the same q.

It is attached to a lipid. I need to see the exam again. Please someone post it up

[kasidji]

Yeah, we really need to look at all the diagrams again to be sure.. did anyone take the exam out? I remember last year people emerged from their rooms with the papers, surely it's just a matter of time.

i have it

[masonnnn]

sorry to go back to it but for the laundry powder question (such a bad question, i didn't study on washing machines) didn't one of the options have a slightly higher ph? like 9ish? i chose that one as i went with the theory that laundry detergent/soap = alkaline...
more chemistry crap and yeah i can't remember the question all that well.
so much longer than last years, i finished last years with half an hour spare, had 4 minutes left over on this to look over M.C -.-

i have it

Willing to post it up?

Yeah I think I chose the 40 degree, highish pH one, because soap is alkaline... but a few of them had high pHs. The temperature was near-impossible to know unless you ever stick your hand inside a washing machine when it's going or are involved in the production process >_<

if you do order them ..do you get them before august 2nd when all the results are released??
when do you get them?

Last year i ordered mine after i got my results, so i got them a month or two later. Although one of my friends ordered his before the exam, and i believe he got his numerical mark a week or two after getting his letter mark at school.

OMFFGGGGGGGGGGGGG I ACCIDENTLY PUT LIGHT INDEPENDENT AND DEPENDENT STUFF FOR THE CELLULAR RESPIRATION CRAP:( down 3 marks ouch

Aw that sucks. A lot of people did that though so don't worry too much.

They cant expect you to know too much chemistry

I believe it was glycolipid:
"
Edit: I just remembered!
The two answers i narrowed it down to were glycolipid and globular protein.

Globular proteins tend to be well... like globs of protein.. many chains like heaped into each other but this was like 1 straight protein going straight up"

Cholesterol doesnt "stick out" of the cell membrane and even if it does... it wouldnt look like a saccharide molecule like this one did (it had like a chain or square or hexagons... how ever they represent it)

[teebagger*]

I went home, collapsed in bed and cried like a little bitch. x__x
My own fault though. Cramming the night before and turning up with less than 2 hours sleep is pretty stupid.

[stonecold]

IMO, hardest exam in the study design to date for unit 3.  Hopefully Unit 4 exam will be easier...

sorry teabagger,  VCAA really are assholes.  Where that exam came from...  VCAA are usually notorious for having easy Bio exams...

[slothpomba]

I would of just given up and got the extra sleep, do you know mark you should of just stole answers off him lol he did pretty good in bio
