|
R = universal gas constant T = absolute temperature z = charge of the ion F = Faraday constant |
| why is the Goldman equation used instead of the Nernst equation to calculate the membrane potential of a neuron | because the neuron is permeable to more than one ion at a time |
| in what situation would you use the Nernst equation rather than the Goldman equation when looking at membrane potentials? | when the membrane conductivity for a specific ion has increased |
| what is the relative membrane permeability for K+ ? | pK = 1.0 |
| what is the relative permeability for Na+ ? | pNa = 0.05 |
| what is the relative permeability for Cl- ? | pCl = 0.45 |
| what is the resting potential of a mammalian neuron? | -66mV |
| what is the net movement of Na+ and K+ during the formation of the resting potential? | 2K+ into the cell and 3Na+ out of the cell |
