    For the Fev one about suggest 2 things which would reduce FEv.

    I put reduced elasticity of the alvieloi

    Less surface area because of scar tissue/alevloi broken down.

    same 👍

    The second last one.
    Just talk about sodium ions and how they are used e.g. AT into the blood, creating diffusion gradient, Sodium ions move in with glucose using co-transport protein, conc gradient of sodium is used to transport glucose against its conc gradient. Glucose conc increases in cells, then passes in blood through channel protein via FD.

    Nicer paper than last year as more content.
    Could not think of 5 mark points for the last 5 marker on diffusion of chloride ions and oxygen

    It was better than last year's exam. The 5 markers were strange though, and I bul*****ed my way through the lipase questions.

    Takes longer to reach the same level

    For the last question:

    Phospholipid bilayer has polar phosphate head which would repel the chlorine and are hydrophilic

    It has fatty acid tails which are hydrophobic.

    Oxygen can pass through because it is a small, non-polar molecule, via diffusion.

    Chlorine requires channel protein because it has a charge.

    Yeah it was a bit weird, but sometimes they award marks for saying specific words e.g. diffusion/phospholipid bilayer.
