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? -.-

No. There is no cancelling out when you're talking about seperate questions. If you had answered, for example...question 12 (v), "Name one substance, other than water, excreted in the urine"...if here, you had said urea and glucose, the fact that you gave one right and one wrong will cancel out. But if you said urea, and then in the next question you get the answer wrong, it doesn't cancel out.

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.

Yes I know that the substrate is and the question was that the substrate was larger than the product. Therefore, this means that the substrate was broken down to form the product. This means that it is Catabolic..BOOM

What I said is true but I got the question wrong in the exam...ahhh ****e. My bad!

State the precise location of the cell membrane in plant cells???
I said surrounding the cytoplasm but that didn't seem very precise...

From the sounds of things, there will be a few changes to the marking scheme. As so many people misinterpreted some of the badly worded questions.

"Reactions in which product molecules are larger than substrate molecule"

Product is larger than substrate, meaning that the smaller substrate is becoming a larger product, which is anabolic.

BOOM, if you will. :P

I said in between the cytoplasm and the cell wall..pretty chuffed with that

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?

that would be the contractile vacuole, acts like a sponge then heads to the edge and squeezes itself it out xD
according to a the best guy in my class and probably year it was the outter cortex. I was fit to kick myself.
Just checked my book an it said medula nd cortex. So as long as we didn't say pelvis, we get it. Sweet.

Thank you, I would have done it myself but I was eating

@Eggy_Baby, I said the exact same thing.

Also, for what kidneys excrete apart from water, would salts count? Totally mindblanked and forgot to say urea.

State one digestive function of the pancreas:

If I just said pancreatic lipase what would I get? Are these questions hit and miss or what?

Edit: It also said "How are the two strands of a DNA molecule joined together?" Is it okay if I took this to mean how are they joined (DNA polymerase) in opposed to what's holding them together?

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.

See i would have done that but at the time i only interpreted the experiment way!

do u know in genetic crosses if you get the parent genotypes wrong but still some way end up with the right geno types for the offspring do u lose marks??

Probably only lose a mark or two

MarkTheBaby

Read through the genetics question a few times. I didn't see where it said that Tall was dominant to short stem. I put them down as neither dominant or recessive like the colour. ...Fúck.

Do you think I'll get the phenotype answer? it just said to write down the phenotype of the genotype you got and I did that right...?

ya you'd loose only three MAX for getting that wrong, its not maths so the wrong process and the right answer should still give u the marks (lets face it the vast majority of bio teachers/correctors are not maths teacher, they wont argue to have it corrected like that).
The marks go for answers not workings out, end of.

Have gotten an A in all my biology test and got an A in the mocks then the leaving cert came along...heya C- if even. I took a chance and analysed last years papers and ruled out what i thought wouldn't come up. Of course my worst nightmare came true and the 7 chapters i left out came up. i was able to answer the recommended amount but not at all in depth. Those questions were awful ecology wasnt nice and where in the world was human reproduction and breathing and nutrition and THE HEART!! That experiment was a load of crap as well anyone else feel my pain

Agreed.

I LOVE Biology and it's one of my better subjects. Felt confident going in then BAM none of the usuals. I understand they might be trying to move away from the predictable topics but that was a real kick in the teeth of a paper. That stupid thing in ecology about the ducks?! What the hell?! And the experiments were an absolute SIN of them. I don't care what anyone says. That was a nasty paper.

Contractile Vacuole.


And, Yes,

Do you think I'd get any marks for saying vacuole ?

Possible 2/3 marks ?

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

Yes, technically, both. I'm not sure how far it went for leaving cert as regards explaining that, but having gone into depth on that particular topic reabsorption definitely occurs in both, as the nephron extends into both parts.

thanks I think it's the only thing I didn't know for sure on the paper..but guessed vacuole...

I was hoping for and A1/A2 on the paper as I'm a repeat and I got B1 last year and A2 in the mock this year.. the experiments were a little tricky though.

I think you'll definitely get marks for pancreatic lipase...production of lipase/amylase would be the most likely answers there.

did zero study, but i honestly think a B is on the cards now. :D

For the "How is DNA joined" I said hydrogen bonds.

I literally decided to drop 5 mins before the exam, so glad I did now

sligo.

i think it was the centromere for the DNA one? the 1st experiment question...unbelieveable SEC...its about experiments on the course you daft Commission!!! but i tried my best and answered all q's on it:rolleyes: some questions were sticky enough, so glad reproduction didn't come. did ye get that the reactions were all anabolic in one of the long questions???

3 minutes before the exam I was literally going to ask for an ordinary level but my friends talked me out of it
Now I have no science subject hence 0% of college and looks like ill have to repeat for what I want but theres no way in hell im repeating so looks like im in a sh** dead end job for the rest of my days

blahhhhh

Ugh I feel your pain... I was an A biology student all year and now I'd be lucky with a B3, if that I just can't believe there was no human reproduction or defence or nervous system! The only good thing about the paper was the genetics question and the short qs... What was with the first experiment question??!!

This is why over analysing exams is no good :P Listen, you don't know how you did, at all. Do NOT adjust your CAO just because you think you failed it. Leave whatever you had as first where it is. A lot of courses don't need any sciences...granted, they may not be the courses you're interested in, but there are options for everything.
