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(:

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?

What would you write for this?
What would you write for this?
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

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

- 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
Pick out whatever makes the most sense to you

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

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...

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

thank you! Still got my fingers crossed for proteins though

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.
