close solutoin list

In the propagation of a nerve impulse: a. the refractory period begins as the K + channel opens, allowing K + ions to flow outward along their concentrationgradient. b. Na + ions flow out of the axon with their concentration gradient. c. positive charges lower the membrane potential to its lowestaction potential. d. gated K + channels open at the same time as the activationgate of Na + channels closes. e. the depolarizing stimulus lowers the membrane potential toopen the Na + gates.
