For the 'how many atp' produced question, what did everyone get? I wrote 36, but I'm starting to believe it was 2.

i said 36 as well.
because didn't it say the net energy production per glucose molecule, which would include the whole process of cellular process, yeah?

I sure as hell hope so... :(

What cell did you put down for the one that differentiates between self and non self? Thats causing such an uproar.

Gahhhh that was fucked...
It was talking about autoimmune disease, and I read that immunosuppressive drugs inhibit the ability of cytotoxic T cells to recognise self from non-self, so I wrote cT cells. I'm thinking that it's not right though because ALL white blood cells can do it? :S
Maybe the were after a less specific answer, like 'white blood cells' lmfao.

Crap I wrote MHC markers. Because I read that thats how the body differentiates self from non self or something, cuz of the antigens on the surface. Quite a lot of people wrote Th cells so I'm guessing you're on the right track. ^_^

well now that most Biologists are here in a group. Can I ask, is Biology worth doing?
A good subject??

I'm finding it very enjoyable, and yes, worth it. :)
Depends I guess.

I like it, but thats because I'm curious and like to know why things happen and in bio you get to understand this stuff.
It's one of the subjects I look forward to during the school week lol.

I did the same as you JL and stated the elements in those compounds.
Anyway
I so gunned it!
The only question which stopped me in my tracks was the one regarding fibrous proteins, where it asked to name an example, and then to explain why the structure of the protein creates a feature of it or something.
:S:S

Else, it was easier than I expected :)




Agreed, I was expecting something out of this world, but that was easy. I'm too cautious to say I gunned it though! And I had trouble with the same question as you..I studied it a long time ago, but blanked out in the exam and left it as I said before..thinking back, the answer is something along the lines of how the chains are generally unbranched, hence allowing them to pack very closely together, making the bonds difficult to break and the protein very strong. Damnn!!! I did chem 1/2 last year, so I should have been able to at least make up an answer to that on the spot.. *slaps self hard*

Nah its not 2, the question clearly stated product of AEROBIC RESPIRATION,
2 ATP is the product of anaerobic respiration (just glycolysis)

the answer should've been 36-38 ATP so youre right

I love bio. I find it fascinating.
I thought the exam was ok.

The calcium concentration question really threw me though.

I ending up putting B, only because I eliminated the others :(

I said MHC markers for the non-self question.

For the fiborous proteins I said because the chains allowed them to shrink/stretch without breaking.

I wrote 36 for the ATP output question as well, because it was asking for the TOTAL output of ATP for one glucose, not just from one stage, but from aerobic respiration as a whole...so I treated the question as including glycolysis, Krebs and the electron transport chain.

memka, I put B for the calcium question too! The options were all quite strange.
