    It was Anabolic-Anabolic-Catabolic btw because if the substrate is larger than the product then it is broken down..i.e Catabolic....
    cant be...
    it said "product molecules are larger than substrate ones"
    so the end product is bigger that the starting one...is that not what anabolic activity is?

    I think you might have misread it, which sucks. It was sort of written backwards... Kind of :p
    Reactions in which product molecules are larger than substrate molecules.

    I said proteinsynthesis was catabolic, and the other two were anabolic.

    I love how it's assumed that not all the answers could be the same! I saw it and said 'they're trying to catch people out'. :P

    Protein synthesis.anabolic

    Conversion of ADP to ATP.(process is in respiration which is catabolic but its ADP+P=ATP , your adding on to make it "larger" so anabolic

    Reactions in which product molecules are larger than substrate molecules. anabolic

    I said there were 9 common amino acids although I knew that there was definitely some group of 20 amino acids. Turns out 9 are considered 'essential', but the full 20 are, obviously, still common... Really annoyed about that!

    Hopefully I answered the rest of the question okay...

    Who in the world decided that this paper should be 3 hours long!?!

    soooooooo disappointed. hated every q thrown on. Got an A1 in the mocks and loved the papers in previous years. This was like they wanted to make it easier by leaving out photosynthesis and respiration for long dragged out equations and q's, but I thought that the q's were seriousy tricky and out of the box. got everything done, all short q's, all experiments (which were weird) and 5 long questions. definitely got some wrong. Oh well!

    It doesn't matter if you got it wrong, if the rest are right, you get full marks. It said on Q1. Answer 5 of the questions below!

    That was literally the only reason I put proteinsynthesis as catabolic haha, I always fall for that one though, I never believe the answers are the same.

    For the children question, I just said that they have a faster heart rate, therefore blood (carrying heat) is pumped around their bodies faster, keeping the extremities and the actual body warmer than it would be in an adult :confused:

    i just said children don't sweat as much as adults

    Name the structure by which Amoeba gets rid of excess water that has entered by osmosis ?

    And does re-absorption take place in the Medulla?

    I actually knew the whole process pretty well. I was hoping there would be a whole part about it but eh well...
    I kinda messed up the kidney question too :S Hated the way it was asked!

    ok, so are we exotherms or endotherms?

    I really wish they'd just use warm and cold-blooded, I'm always getting confused with this.

    yeah but in fairness I'd say that was probably my strongest question. I knew the whole body really well, the biology i love, but hardly any mention of the systems. Just crap, there goes my A

    Exam paper is up on examinations.ie atm

    It was Anabolic-Anabolic-Catabolic btw because if the substrate is larger than the product then it is broken down..i.e Catabolic....
    Substrate is what the enzyme works on.
    Product is what is made by the enzyme-substrate complex.
    If enzyme works on a substrate, and makes it bigger. It adds to it.
    ie. Anabolic reaction.

    Do u know for this question

    "State two different uses of a water bath in biological investigations"

    My whole school is split with what the answer is half of the people including me think its the experiments u used the water bath in but the other half think its what was the water bath used for............?? any ideas because u cud pick it up both ways!!

    I think I read that as "ATP to ADP". FML, that'll be annoying me the whole summer.

    And that's also going to cancel out one of my correct answers isn't it? -.-

    I would have read it as 2 different functions, rather than 2 different experiments. I'd say they would accept the other one if you had said "Used in X experiment to heat the test tube to 40 degrees" and "Used in Y experiment to keep the solution at ..."

    It wasn't that clear at all was it, i said the experiments themselves but I'd say you'd have to get marks for both because it really wasn't clear

    I think it could probably be interpreted both ways, but the safest option was to give the use, with an example of an experiment with this use. Covers all bases.

    Doesn't some re-absorption occur in both the medulla and the cortex? Hope so :confused:
