    I said when the vesicle moves through the cytoplasm...I guess that's wrong? Man, I got too many wrong. I'll be so lucky to get a D.
    unforrtunately so . Exocytosis is specifically when the vesicle fuses with the membrane

    NB: New point to everyone! IF IT WAS A SPIROMETER THE AIR VOLUME WOULD HAVE DECREASED!

    It wasnt a spirometer.

    It said volume of air in the lungs.

    So that meant between Points a and b the volume is decreasing so therefore it wants EXHALING

    exactly! I found it harder than the biology unit 2 as resit i did in january, and that one is meant to be harder! As soon as i saw that spirometer thing i died a little inside, why do they love putting that in there?!
    Same!! I did that resit too in January! Urgh, i hated the artery and spirometer question! Don't understand how people can call this paper easy. :confused:

    okay, so what did you put for the one about residual volume? i was absolutely clueless...

    eventually as the air is being exhaled, the pressure gradient will diminish thus some air will be left in the lungs without a pressure gradient thus it does not flow out
