Q. The action potential of a neuron (influx): (Solved)
1. is initiated by efflux of Na+
2. is terminated by efflux of K+
3. declines in amplitude as it moves along the axon
4. results in transient reversal of the concentration (?electrical) gradient of Na+ across the cell membrane
5. is not associated with any net movement of Na+ of K+ across the cell membrane
- e. is not associated with any net movement of Na+ of K+ across the cell membrane
