Biology Exam: Answers and Discussion!

Ha...Ha....Ha...

It's not unheard of, a few VCAA past exams I did gave full marks to everyone if the question wasn't clear.

Hey guys are these answers 100% verified because for question 12 it seems like the answer would be B rather than D? If I'm wrong could someone explain why it would be D? Thanks

Yeah I put in B... but it seems like everyone put in D and the explanation seems legit. Meh.

[vcestudent123]

Maybe VCAA will be nice and award everyone full marks for that question 

Crazier things have happened...wait no... nothing is crazier than that.

Hey guys, to everyone who messaged me for a copy of the exams multiple choice, I will send them to you ASAP, I just haven't had my laptop with me all day. Sorry about that!!

The conversion of pyruvate to acetyl-CoA is a part of aerobic respiration, as pyruvate oxidation is included in the krebs cycle in VCE bio

2011 Biology Exam Paper 2 (Unit 4)

The very first question.

There was a picture of a cell with different things as Structure __, Structure ___.

In which structure would RNA Polymerase be found?

Problem was, the nucleus didn't have a structure name attached to it - full marks for all. I doubt they're going to this time though

It's happened...

Also when do VCAA release their solutions?

Is it on the same day as we get our results?

Ah okay fair enough. I guess cos we weren't taught the whole process of pyruvates being converted to acetyl coA at our school :/ and I thought that if the cell naturally used glucose as an energy source it was only possible that the most ATP produced would be through the normal process. But now as I'm typing this I just realise that lipids store more energy than monosaccharides so option D does make more sense. Thanks for clearing it up!!
so I know for certain I've gotten one wrong in MCQ. :/

It's happened...

Oh wow, I take it back.

I still have hope of gaining marks for this exam.

I'm so angry at myself because of the amino acid question.

Apparently the answer to the number of nucleotide bases was 273 including the stop codon.

Did anyone else write 270?

I wrote 270 as well, to find out by my peers that the answer was 273 due to the "Stop" codon, i felt the rage rise up in me.

Why? Hardly anyone I know got the full mark for drawing an amino acid... TBH as I've said before that there is a tiny chance that VCAA turn around and say "hey look, kids who did chem 3/4 had a major leg up on kids who haven't done it, so we'll give everyone the mark"

And lots of other people wrote 270

I also had a look in the study design, and nowhere does it say that we need to know the exact structure of an amino acid.

I wrote 270 nucleotides for the monomers and 3 nucleotides for a stop codon. I didn't say '273' per se, but I hope it suffices haha.

Truth.
