The sequence of events that constitute an action potential is correctly described by which of the following? Resting potential of…..
- +35 mV, stimulus above the threshold, Na + move into cell, depolarisation to −70 mV, K + move out of cell, repolarisation to +35 mV.
- −70 mV, stimulus above the threshold, K + move into cell, depolarisation to −35 mV, Na + move out of cell, repolarisation to −70 mV.
- +35 mV, stimulus above the threshold, K + move into cell, depolarisation to −70 mV, Na + move out of cell, repolarisation to +35 mV.
- −70 mV, stimulus above the threshold, Na + move into cell, depolarisation to +35 mV, K + move out of cell, repolarisation to −70 mV.

D: The resting potential is negative, and the fi rst ion movement is sodium ions into of the cell.
