Membrane Potentials Flashcards
1
Q
Direction of ion flow
A
2 potassium in, 3 sodium out
2
Q
Maintenance of membrane potential
A
sodium ions leak into the cell slowly and potassium ions leak out of the cell quickly
Since more
3
Q
inside of membrane
A
negative charge protein and potassium ions
4
Q
outside of membrane
A
sodium ions
5
Q
sodium-potassium pump
A
3 sodiums pumped back out and two potassiums pumped back in
6
Q
leaky membrane
A
lots of potassium leaks out and a bit of sodium leaks in, leaving the inside of the membrane negative
