2- a) Assume the following concentrations of Na+ and
K+ ions: [Na+]o = 120 mM,
[Na+]i = 6 mM, [K+]o =
2 mM, and [K+]i = 150 mM. Assume further that
at the peak of the action potential, pK
: pNa is 1 : 12. Calculate
Vm at the peak of the action potential.(Use
Goldman-Hodgkin-Katz equation, disregard Chlorine
ion)
b) Explain the molecular basis of the neuronal refractory
periods. That is discuss both the absolute refractory period and
the relative...
