b c d 13 During first phase of action potential Depolarization Permeability of ions is not changing Permeability for K and Cl ions decreases for Na stays the same Permeability for K and CI ions stayes the same for Na ions increases Permeability for K and Na ions stayes the same for CI lon decreases 14 If irritation stimulus is strong above threshold b a large amount of Na ion channels open that is enough for reversal of membrane potential Small amount of Na ion channels open that is not enough for reversion of membrane potential large amount of Na ion channels open that is still not enough for reversion of membrane Small amount of Na ion channels open that is enough for reversion of membrane potential 3 15 Which of the following channels are active in the phase of repolarization Voltage gated K channels and non gated K channels Voltage independent Na channels and Na channels Only voltage independent K channels Only voltage gated Na channels
