An action potential is regarded as an example of a positive feedback. Which of the following examples below best illustrates the positive feedback aspect of an action potential?
◦ Voltage gated potassium ion channels open slowly and remain open long enough to cause hyperpolarization.
◦ Potassium permeability is about 25 times greater than sodium ions.
◦ A threshold stimulus will cause the opening of voltage gated sodium ion channels that will cause further depolarizing stimulus. This stimulus will open still more voltage gated sodium ion channels.
◦ The sodium potassium pump consistently moves ions as long as ATP is available, and regardless of membrane potential changes.
