AQA Biology 5 - 23rd June 2015 - Essay: Predictions & Past Essays

I thought a thread like this might help for the unit 5 essay coming. Post your predictions, and I will update this post. I'll also add previous essays later.

It'd be really helpful if, with your predictions, you include topics that could be written about it.

To keep the thread tidy, here are some predictions:

These are taken from MrPollock's 2015 predictions video.

•

Proteins (was on the original 2015 paper but they had to use the R paper instead)

•

Ions
1) Co transport of glucose - Na+
2) Na+/K+ in maintaining a resting potential and propagating an action potential across a neurone
3) Ca2+ - synapses
4) Ca2+ - muscle contraction
5) Cl- - maintaining WP in lumen of small intestine (link to cholera)
6) H+ - oxidative phosphorylation in aerobic respiration
7) H+ - buffer system in blood, linked to nervous control of heart rate
8) Mineral ions in plants - lower WP in root hair cell, promote water uptake
9) Nitrate ions, phosphate ions - proteins, DNA
10) Mg2+ - chlorophyll production
11) K+ - cell maintenance
12) Fe2+ - haemoglobin and transport of O2

•

DNA technology

•

CO₂

•

ATP

Predictions from the general thread:

•

Importance of the movement of molecules in biological systems

Spoiler

•

Movement inside cells.

Original post by cherrybanana

- Water movement in plants

- Chromosome movement
- Neurones and synaptic vesicles
- Actin and myosin
- Movement through ER and Golgi
- Protein synthesis
- Electron transport chains
- Ion movement

•

The different ways in which living organisms obtain their nutrients.

Original post by cherrybanana

- Gas exchange

- Carbon cycle
- Nutrient cycles
- Nitrogen cycles
- Photosynthesis makes glucose
- Balanced diets
- Foetus-placenta
- Xylem: water uptake by plants
-Digestion and absorption

•

CO₂

Original post by hopingmedicinae

-Affects breathing - could describe Biol1 how the body moves to remove Co2
- Carbon Cycle
- Differences in night time and day time
- Climate change- effect on crops, animal species - distribution of animal species
- Light independant reaction
- Co2 and chemoreceptors
-Haemoglobin and Bohr Shift
- Agricultural farming - greenhouse conditions e.g burn propane to form Co2
- limiting factor in CO2
- causes of increase, agriculture, deforestation (getting rid of carbon sinks, photosynthesising biomass)

Good idea for this thread, hey would anyone want to do an essay swap - i need one on the causes and importance of variation and diversity in organisms as that's the one i haven't yet done.

I thought mr pollock had not yet done a predictions video though?

He hasn't, these were his predictions for last year :smile:

but I suppose they're still likely for this year

I don't particularly like CO2 being involved in an essay title, there's relatively few topics to talk about

Added this. I think people expected this to be on the normal paper but since it was leaked I'm guessing we'll get different titles

I might go up and kiss an invigilator if it does come up on the exam though :')
