Biol5 essay predictions and thoughts for June 2012

Hey(:

I created this thread purely for the essay at the end of biology unit 5 AQA, so we can all discuss our predictions for the essays and share ideas of what we can add into each predicted essay question(:

So... if anyone has any predictions join in(:

I pray for enzymes/proteins but know that won't happen. :biggrin:

That'd be a good one!(: I'm holding out for one on nitrogen. And that could happen, don't think it's been a question in the new spec(:

Proteins is actually a hot topic to come up judging from predictions from other people. Also a lot of people have been saying inorganic ions or ATP may come up...this would explain why my teacher gave us the ATP essay to do, maybe as a hint?

I hope they give us a nice one though, but can never tell with AQA examiners!

Something on ecosystems in general!!

The inorganic ions one is my top favourite. Also maybe something to do with variation/diversity?

i got an essay title from my teacher on the transfer or energy through ecosystems and living organisms

What could you write for the ATP one? :smile:

What would you write for this?

Any process that involves ATP I guess, so that is quite a lot.

What would you write for this?

Hydolysis of ATP - energy transferred, used in other processes

Photosynthesis - light dependant reaction - photolyisis - light independant reaction - glucose produced

Plants - producers - energy transfer to primary consumer - decomposer activity

respiration - glucose from light independant reaction used in glycolysis - phophorylated by phophate ion - formation of reduced coenzymes - link/krebs cycle

ETC - energy released used to pump H+ ions across membrance etc.

you could say ATP from respiration used in maintaining resting potential - muscle contraction. Then link this to heat losses, so less energy available to secondary consumers etc.

thats all i could think of. Hope that helped you :biggrin:

Ooh, originally I thought this would be a pretty narrow essay, but you've changed my mind. Thanks! :smile:

aha, thats what i thought at first, but when you start with the simplest points like ATP, then everything else starts to fall into place with each point following from the other. I generally start with plants first when i do the essay, this way the carbohydrates produced in photosynthesis i can use in other processes so you can link more than you originally thought you could :biggrin:

This is the plan my teacher gave us:

- In respiration- glycolysis
- Active transport
- Ions in neurones
- resting potentials
- Synapses (regeneration of neurotransmitter)
- Uptake of sodium and glucose by co-transport protein in the gut
- Muscle contraction- make myosin heads return to normal position and reabsorb calcium ions back into sER
- Movement of flagellum of sperm (?)
- Protein synthesis- activates amino acids/ condensation reactions e.g glycogen synthesis

-Endodermis ions into xylem
- Root hair cells uptake of some ions by active transport
- Nitrogen fixation
- Photosynthesis- LIR- ATP used to convert GP to TP
-Regenerates RuBP
-ATP needed in cell division

Hope that helps :biggrin:

Pick out whatever makes the most sense to you :smile:

What would you write for inorganic ions? I can think of Ca2+ in muscles, Na+ and K+ in nerves and ammonium/nitrites/nitrates in the nitrogen cycle, but I've reached a dead end there...

Yesss this did help, thank youuuu :biggrin:

But in conclusion I hope this doesn't come up XD

You could talk about:
Hydrogen- Photolysis, ETC
Phosphate- ATP, Glycolysis
Chloride- epithelial cells, CF
Iron- Haemoglobin and how it's linked with the uptake of Oxygen

Hope this has given you some more ideas :biggrin:

I didn't think of any of those :s-smilie:

thank you! Still got my fingers crossed for proteins though :smile:

I'm scared =(

Anytime

Ahhh complete opposite of me! I'm rubbish at writing about proteins XD but let's say one should be proteins and one should be inorganic ions :P I wouldn't mind ATP or variation either...Ecology is gonna be a nighmare for me.
