    Ahhh nicotine can have fatal effect....it takes the shape as the sodium ions. so it can bind with sodium receptors on postsynaptic membrane continuously creating action potentials. organic phosophorous fertilizers can inhibit the enzyme acetylcholinsterase thus creating continous action potentials.

    where as botox has the opposite affect.

    it is the most boring stuff ever.

    what does nicotine, botox and orangic phosphorus do to nerve transmitters? i must have been off when we covered that or something :confused:

    Nicotine has same shape as the transmitter substances and binds down to the protein receptors on the post-synaptic end for a longer time,as they dont break down easily which means a continuous flow of AP.
    BOTOX: botlinum Toxin is a toxic made by some bacteria anaerobically, where i believe it inhbits the exocytosis of vesicles to the cleft, while fertilisers such as organic phosphorous inhibits acetyl cholinesterase causing a continuous fire of AP.

    Functions Of Synapses

    1) one way flow of action potentials
    2)divergence and convergence of nerounes (i.e 1 nerone to many) or (many nerones to one)
    3)low generator potentials can be ignored
    4) all or nothing action potential

    You can call it Rubisco Bisphosphate then abbreviate it to RuBP.
    It's ribulose bisphosphate.. rubisco is the enzyme...

    i dont know, but if we do...then i think we might need to know about glycogen phosphorlase aswell...they dont explain it well in the ocr biology book. does it say in the spec?


    ignore the complex stuff and look at the overall picture
