0
Q
What does the sodium-potassium pump do?!
A
Moves three sodiums out for every two potassiums ion
1
Q

A
Large intracellular protein
Na/K pump
Sodium ions
Potassium ions
2
Q
How can channels be opened?!
A
Chemical
Voltage changes
Mechanically
3
Q
What does the Nernst equation calculate?!
A
Eion
It cannot calculate the resting membrane potential
4
Q
What does the Goldman Hodgkin Katz equation calculate?!
A
Membrane potential
5
Q

A
Potassium - due to selective channels in the membrane
