1 B. In the actual case in which the ACh receptor-channel is permeable to both Na+ and K+, experimental results show that the end-plate current reverses at 0 mV because the ion channel allows Na+ and K+ to move into and out of the cell simultaneously (see Box 9–1). The net current is the sum of the Na+ and K+ fluxes through the end-plate channels. At the reversal potential (EEPSP) the inward Na+ flux is balanced by an outward K+ flux so that no net charge flows.
