Who felt like they were ripped off a bit today.

I felt like the writers excluded sections of the course such as plant hormones and rational drug design. In every other year, rational drug design had been on the exam and I'd usually seen a plant hormone question as well.

So bad

I just studied my butt off and this exam was soooooo blah and now I read all your answers and confidence level drops 10 points :p

You're not alone, I feel exactly the same to be honest.

I think I wrote it can immunise the person upon return to Australia and then the person can be quarantined for a short period of time.

oh that was a different question, there was one about how the adults were infected with the disease dispite being immune, and we were asked why this was the case, i'm asking about the question following on from this :), and how we can treat this issue or w/e

Ok. I think I get the polypeptide question now!
When the meat is ingested, the pepsin breaks down proteins(meat) into smaller polypeptide chains. Then the protease breaks down smaller polypeptide chains into amino acids. So i think the level of polypeptide concentration for 10 and 80 degrees will be lower than the 37/35degrees.
That is what i thought. I might be wrong though.

i swear i;m seeing people talk about this so much. i made 10 higher than 37 and 80 highest, because at 10 deg, enzymes aren't working at optimum, therefore less polypeptide chains are broken down (proteins are polypeptide chains i think), therefore there is MORE polypeptides present therefore it is at a higher concentration than 37, at 80 the enzymes are denatured blah blah blah. lol.... idk i think i'm wrong so dw about me

Yeah that's true as well. But before that protein can also be broken down into smaller polypeptide chains before amino acids because you need a few different enzymes to break a protein. If yours is correct, then shouldn't both be much much higher than the 10degrees one given that the 35/37 ones is already high enough.. this question can be really misleading somehow. I was just hoping I could argue over with them to accept both answers.

the question mentioned a protein meal.   Since pepsin in the stomach only breaks protein down into polypeptides not amino acids I suspect the 10 and 80 should be much lower since enzyme is denatured etc, etc.  Strange question though - how the hell do you measure a polypeptide concentration as opposed to a protein concentration since these are the same thing only differing in terms of shape!!!!

the table ask us to graph the polypeptide concentration, not aminoacid, in the person, so it would be high at 10 and 80  ???

Here's why we can't trust any answer. VCAA gave this as a solution to question 25 MC 2009.

Step R involves peptidases converting proteins (polypeptides) to peptides;
hence options A and B were incorrect.

They called proteins polypeptides.

terrible! vcaa is terrible! they said in a VCAA assessor's report that macrophages are lymphocytes! they arent -.- now they got that stupid compound thing wrong! that confused the crap out of me!

VCAA also said that ethylene and ethene are not the same thing when they clearly are AND they went on to say that ethene is NOT ORGANIC! WTH!
