WebJul 7, 2024 · Why can’t action potentials flow backwards? This means, that as the action potential passes forward and causes depolarisation, it cannot flow backwards as there is the influx of potassium. This means it cannot pass backwards, once the impulse is in the axon. Why does the K+ conductance turn on slower and last longer than the Na+ … WebNov 17, 2024 · Can action potentials travel backwards? This means, that as the action potential passes forward and causes depolarisation, it cannot flow backwards as there is the influx of potassium.
