Electrical Properties of Cells Flashcards
1
Q
What are the different types of electrodes?
A
Intracellular
Extracellular
Patch clamping
2
Q
Why are electrochemical gradients established?
A
Because pumps move ions against their concentration gradient
Because there is restricted ion movement through channels
Membrane stores ionic charges on its inner and outer surfaces
3
Q
Features of an ion pump?
A
Uses ATP
Every 2K+ that enter 3Na+ leave
More K+ during an action potential inside the cell
Electrochemical gradient established due to pump
