Ah, one mark down.
Yup, aerobic respiration specifically if I never remember wrongly. As anaerobic respiration takes place in the cytoplasm or something.

And yeah i hate this paper. I think i will fail. I spent too much time studying eye and egentic that none came out. WTF! Lousy paper. seriously arent exam papers' purpose to test if you know your content well? 2 chapters not in. what is this sheet.
Rough Endoplasmic Reticulum, I think. Although if you've handwriting like mine, I don't think they'll know if you wrote 'Reticalum'.

Whoa, dude, you've really done homework!
Originally posted by iamapebble:Relax. Yes they are but come on, look at the amount of questions they can set, they can't possibily include all 22 chapters.
Fail? =/ Was it that bad..? Other than the cell maybe you have forgotten but others?
hmm let me think.
1) I didnt know what the bush of the flower was. Why didnt i just write stigma? zzz. -1
2) The shape of the pollen grain i wrote small but didnt write light. -2
3) I dont know whats with a wind pollinated flower so i said the anthers are dangling in the air. And the bushes trap pollen. -2
4) I wrote hypothalamus senses the glucose concentration -2
5) i forgot what causes prothrombin to turn to thrombin and fibrinogen to turn to fibrin threads. In retrospect, i think i spelled fribrinogen. -3
6) cant spell RER. -1
7) normal carelessnessessssss. -5
Btw, one impt thing. for the graph do you join the dots or draw a curve. or line of best fit.

This is correct.
3) I dont know whats with a wind pollinated flower so i said the
anthers are dangling in the air. And the bushes trap pollen.
This is also correct.
5) i forgot what causes prothrombin to turn to thrombin and fibrinogen to turn to fibrin threads. In retropspect, i think i spelled fribrinogen.
You don't lose all the marks even if you forgot about thrombokinase.
1) the feathery thing is stigma
2) light/small/smooth/produced in abundance
3)the stamens are pendulous + the stigma is large/extended and feathery
4) the islets of Langerhans are stimulated
5)remember the process of converting prothrombin to thrombin with thrombokinase requires Ca+ ions
6) =(
7) =((
i drew line of best fit cos i saw some sample Q which was similar wif best fit lines.

I didn't write about the calcium ions. Are you sure that's needed?
Plus, I wrote that the pollen grains have wing-like structures to aid in wind-pollination. I'm not so sure, guess I mixed up seeds and grains...
I drew a line of best-fit because it was impossible to draw a curve.
my teacher stressed on that.
pollen grains (some) have wing like structures, seen in some structured Q before, so maybe accepted.

Ah, good. Good.
- It's okay :)
3) I dont know whats with a wind pollinated flower so i said the

- Definitely correct, as for 'bushes trap pollen', don't sound exactly correct, perhaps they'll give you the BOD.
4) I wrote hypothalamus senses the glucose concentration
- It is true, it is because the blood is concentrated and it travels to the brain and then the hypothalamus senses that the concentration of the glucose is not right and then it will send signals to the Islets of Langerthans inside your pancreas to produce insulin. Vice versa for diluted blood.
5) i forgot what causes prothrombin to turn to thrombin and
fibrinogen to turn to fibrin threads. In retrospect, i think i
spelled fribrinogen.
- Spelling wise I guess penalised, but I don't think forgetting thrombokinase is a very big matter, don't have to penalise yourself too much.
--------------------------------------------------------------
I drew a curve because I remember the specimen paper was something like that. As for Ca+ ions, I don't think that's necessary too.
Oh yeah! What are the components of blood that prevents entry of microorganisms? I wrote fibrin threads and RBCs (since they're part of a clot) at first but changed them to fibrinogen and white blood cells. Since fibrin threads aren't part of the blood but are formed from soluble fibrinogen, which is part of the blood. And since there's phagocytosis and production of antibodies by white blood cells which kill foreign bacteria... But I'm not sure if they'll accept white blood cells since it doesn't BLOCK microorganisms from entering the body but rather prevents them from spreading. I just thought RBCs was a little lame for an answer :P
actually thrombokinase is a big matter, cos without thrombokinase the clotting process can't occur.
+ islets of Langerhans are the receptors for blood glucose regulation, im sure bout this.
the Q asks with 2 key tasks: protect the body, prevent the entry
so the ans is platelets n WBCs (phagocytes/lymphocytes)

Hmmm, I wrote platelets and plasma. Because white blood cells yup, do not block micoorganisms from entering. Plasma produces the thrombokinase right..? Can't remember, haha.

Hmmm, the thrombokinase thing, I guess so.. but davidche don't have to penalise the whole 3 marks I guess.
Yup islets of Langerhans are the receptors, but hypothalamus is the one that detects that the blood condition is not right, if I'm not wrong.
Hmmm about the question, I thought I only saw the emphasis on preventing the entry that's why protecting the body, so I didn't write WBCs.
Originally posted by iamapebble:Hmmm, I wrote platelets and plasma. Because white blood cells yup, do not block micoorganisms from entering. Plasma produces the thrombokinase right..? Can't remember, haha.
Haha platelets produce thrombokinase. I hope they'll accept fibrinogen, which is unlikely. Anyone thinks otherwise? *is hopeful*
actually receptors detect the change, but I don't see any wrong if one did or did not write hypothalamus
its damaged blood vessels, tissues and platelets that release thrombokinase, not plasma
+ i would really like to know who did 11 E cause its damn difficult
I hope occam's razor is correct I wrote WBC & blood platelets too!

Hmmmm, I guess you have to hope that you are not 1 mark -touch wood- away from your A1 or something can already :)

Ahhhhh I see I see :D So I'm wrong! Haha. Anyway the part on hypothalamus, it's because davidche wrote that and thought he was wrong, so I'm telling him that it is actually correct. :)
I saw the E and immediately went to do O. Hahaha!
the enzyme Q im in doubt (3m sia )= )
the Q asked to draw the molecules present after complete digestion of proteins
so i drew amino acids, seemed like my class half amino acids, half polypep
the following Q asked what type of enzyme is involved in this digestion
so i put protease.

I drew everything broken up, HAHA. Yeah I put protease too. My friend put pepsin.

I was confused by the freaking complete digestion too. But I didn't go with my instinct so I drew polypeptides, which I think a.a should be right actually.
Type.. I wrote it's a type of protein. T.T
i wanted to leave a note like ultima previously suggested, but too lazy.
I heard if moderate a1 cant go beyond 85, is this true?

I wanted to too after I checked the paper thoroughly, which is.. when I have to stop writing. =[
Is it.. but I thought maths can easily go up to 90..
