Resting Potential Flashcards
1
Q
When a cell has resting potential, how is its composition?
A
Inside is more negative than the outside
2
Q
Resting Potential relates to the
A
Gradients of ions across the cell membrane
3
Q
What are cations important for neuron functions?
A
K+ and Na+ and Ca2+
4
Q
K+ has a higher concentration
A
In the neuron
5
Q
Na+ and Ca+ have higher concentrations
A
Outside of the neuron
6
Q
What are anions important for neuron functions?
A
Organic anions and Cl-
7
Q
Organic ions have a higher concentration
A
Inside the cell
8
Q
Cl- is much higher
A
Outside of the cell
9
Q
What are forces that drive neuron across the membrane?
A
- Electrical force from membrane potentials
- Chemical / Diffusion Forces that relate to the concentration gradients
