5 terms

which ion's conductance dominates the resting membrane potential?

K+

what does the Na+/K+ do?

takes in 2 K+; move out 3 Na+; active transport because uses ATP

which ion fluxes at the start of the action potential?

Na+ influx

equation for V_m

V_m = sum(E_i * g_i)/sum(g_i), where g is the total conductance

Nernst equation

E_x = RT/zF * ln(Xo/Xi)
