Select ALL statements that correctly describe events that occur during an action potential. a. Sodium-potassium pumps are activa
ted when the membrane potential difference overshoots the resting potential. b. When voltage-gated Na channels are open, voltage-gated K channels are closed. c. When voltage-gated K channels are open, potassium ions (K ) move out of a neuron. d. Sodium ions (Na ) move out of a neuron in the first phase of an action potential, and then flow back into a neuron at the end of an action potential. e. Opening of voltage-gated Na channels causes more voltage-gated Na channels to open. f. Reaching the peak membrane potential reversal inactivates voltage-gated K channels.
Action potential describe rise or fall of membrane potential of a particular cell location. This happen when neuron send impulses away from cell body. During action potential, one of the neural membrane opens so as to allow positively charged ions inside the cells and negatively charged ions to move outside the cell.
