Question

During an action potential, which of the following changes significantly? Group of answer choices

Answer 1

The process is ocurring by steps, starting with depolarization.

1- Na+ permeability > K+ permeability

2- Vm (membrane potential) approaches ENa+ (quilibrium potential for potassium)

3- K+ permeability > Na+ permeability

4- Vm (membrane potential) approaches EK+ (quilibrium potential for potassium)
