Acetylcholine? and more.?

What is acetylcholine? Also tell me its effect on the plasma membrance of a muscle cell.

If the water molecules inside and outside a cell suddenly become hydrophobic(nonpolar), would the transport of materials into and out of the cells be affected? and how is it affected?

Just help me on these two I don't get. I think I got the second one, but I just wanna double-check.

Update:

Hey, I have no clue on the first one and I think I kinda got the second one. Grr.

    Acetylcholine is a neurotransmissor, it's released by neurons and it acts in the plasma membrane receptor, it's the way the communicate.

    The second one doesn't make any sense, water will never be hydrophobic.

    Well if you just want to to "check" then post your answers here and we will check them for you.

    That sounds fair.

    EDIT>>

    I repeat, post the answers you have so far and we will check them.

    You might find some mug gullible enough to do your homework for you, but I doubt it.
