After-hyperpolarization phase

Which of the following ion channels are responsible to generate and propagate * action potential? 0 leakage ion channels 0 ligand-gated ion channels O mechanically-gated ion channels O voltage-gated ion channels 2. Which of the following is correct about the after-hyperpolarization phase? * O Membrane potential at this phase is more positive than that of the resting membrane potential. 0 This phase occurs during the absolute refractory period. O Action potential can be triggered if a suprathreshold stimulus is applied. 0 Sodium channels are opened whilst potassium channels are closed.
