Action potential 0.0 / 5 ? Applied ScienceBiologyBTEC NationalAQA Created by: Lewis3674Created on: 09-01-20 12:47 What starts an action potential? A impulse 1 of 11 What happens at depolerisation? Sodium channels open 2 of 11 How is the PD(potential difference) affected at depolerisation? The PD increases 3 of 11 What happens at repolerisation? Potassium channels open 4 of 11 How is the PD affected at repolerisation? The PD decreases 5 of 11 What happens at hyperpolerisation? The PD goes below resting potential 6 of 11 What happens to the PD at hyperpolerisation? The PD goes below resting potential 7 of 11 What happens if the impulse does not reach the threshold? It goes back to resting potential 8 of 11 What is the PD of resting potential? -70mv 9 of 11 What is the PD at the threshold? -45mv 10 of 11 What is the PD at repolerisation? 40mv 11 of 11
