I think out of that list

• Lipids (the only unit 1 nutrient not yet done)
• SA:vol
• Hormones
• Gaseous exchange
• Genetic engineering
• Stimulus/response
• Active movement across the membrane

these are feasible just merge all the genetics to one side, i plan to revise genetics alot! it came up so much in module 4 and even 5 they seem to be genetics obsessed! and then stimulus/response has alot of breadth within the A2 course. The ones i cut out i just believe to be to narrow for them to ask

Stimulus/Response seems too narrow. The rest are real possibillities. Gas exchange is really sticking out for me.

not really because EVERYTHING tends to have a stimulus to provoke a reaction.

I'm considering doing that, although I'm worried that I'll be focussing too much on the essay titles and then completely lose sight of what the questions are asking, so I'm in a bit of a dilemma really.

i thought it might be how the shapes of biological molecules are related to their functions

my teacher's an examiner for aqa b and she told us that this is a real possibility

If we got the Lipid one what exactly would you put?

Metabolism, Bile, Lipase, Micelles, Chylomicrons... then i'm stuck

Can you talk about phopholipids etc as well?

Also do Lipids enter lacteals which form lymph vessels and join the blood stream under the arms at the left and right subclavians?
