Exam Discussion

yes pig was correct,

someone tell me something to feel better lool (realizing the marks lost) rofls.

For the polypeptide question i wrote both lower. If at 37 its such a high number and its optimum level for reactions, doesnt that suggest that polypeptides are the products or protein breakdown? Hence, at 10C enzymes are working slower to produce the product and at 80C enzymes are denatured

[ILiekMudkipz]

Agglutination happens when ppl donate blood to the wrong blood type right?
THAT WAS LIKE 3 OF THE ANSWERS.

But aren't proteins polypeptides?

that's what i thought lollll i don't think i read the table right

that's what I thought, but it asked for concentration of polypeptides, not ammino acids

Isn't meat in proteins like tertiary structure? And polypeptides the broken down primary structure? I understand the reasoning about polypeptides being proteins but why would 37 show such high levels? Its like 37 doesn't breakdown proteins? I just figured breakdown to amino acids happens in the intestines

yeah that's true, 37 should have been really low then :S

You have nothing to compare it to, how do you know its not already low? =/

How much was that polypeptide question worth all up 4 marks? 2 for graph 2 for explaination?

[ChickenCh0wM1en]

Yup, 2 marks for the drawing on the graph,

2 marks for the explanation.

Did anyone find this question ambiguous or confusing? Quite a few people at school interpreted it differently?

Im pretty sure the graph is worth 2 and the explanation is worth 2

True but it said the results were after 10 hours. After 10 hours would there be any material that hasn't broken down? I think if the explanations are correct either a higher or lower response can be accepted

For the 1st SA question. It had an electron micrograph like this http://umanitoba.ca/Biology/BIOL1020/lab3/images/PlantCell-Micrograph1.jpg - It asked for structure X, I wrote cell wall because it was relatively thick in comparison to the large mitochondrion? But EVERYONE else chose cell membrane..... they said they didn't see any chloroplasts....but it doesn't have to have chloroplasts to be a plant cell like the root cells that are plant cells despite having no chloroplasts? UGH, am i being a smart cookie or naive student? I hope it's the first 

[zKskita]

Just to be clear for myself and pretty much everyone else, is this correct?
