Why are action potentials usually conducted in one direction? a. Ions can flow along the axon in only one direction. b. The brief refractory period prevents reopening of voltage-gated Na+ channels. c. The axon hillock has a higher membrane potential than the terminals of the axon. d. Voltage-gated channels for both Na+ and K+ open in only one direction.

Hello everyone here We have a question asking us what causes an action potential to propagate in a specific direction along the axon. A. The refractory period following activation in the sodium channels. Be the differences and charges along the axon. See opening the sodium and potassium channels at the same time or d keeping the sodium channels activated all the time. Their factory period following activation in the sodium ions or the sodium channels causes an action action potential to propagate in a specific direction along the axon. During this refractory period of sodium channels after activation, they cannot open again so that causes it to be uni directional. So our answer here is a thank you for watching. Bye.
