Membrane Potential Flashcards
1
Q
What driving force is responsible for generating a cell’s membrane potential?
A
electrical driving force
2
Q
What is electrochemical equilibrium potential?
A
chemical driving force is opposed by electrical driving force result in no net movement
3
Q
What can the Nernst equation tell us?
A
strength of chemical driving force –> equilibrium potential
4
Q
What unit is equilibrium potential in?
A
milivolts (but remember it gives the strength of chemical driving force)
5
Q
What unit is membrane potential in?
A
Vm
6
Q
Resting membrane potential is primarily determined by which ion?
A
K+
