Question

You are tired from listening to you idiot biology professor. As you exit the class you trip over a class mate trying to run from the room and hit your head on a cement girder. Place the folowing actions in order from hitting your head:

1-The sodium-potassium pump changes shape and 3 Na+ ions are expelled back outside of the nerve.
2-The electrochemical gradient is restored.
3- K+ binds the sodium-potassium pump.
4-Sodium rushes into the axon of the nerve.
5. You pick yourself up off the ground and go back home to bed, biology sucks....
6. ATP is hydrolysed to ADP putting a phosphate group onto the sodium-potassium pump.
7.Anions in the nerve axon move towards the increased positive charge and cations move away opening adjacent Na+ ion channels, thus relaying the signal down the axon to activate other nerves or muscles.
8.The sodium-potassium pump binds Na+.
9.Nerves in your head trigger the opening of Na+ ion channels
10.ADP is released from the sodium-potassium pump and the pump changes shape and 2 K+ ions are released into the cells

Explanation / Answer

9,4,7,5,6,8,3,1,10,2 just use this as a reference for your probably more correct answer Oh and ATP is not amphipathic simply because the term amphipathic describes a molecule that exists with a non-polar side and a polar side for example a phospholipid
