For a cell to undergo an action potential, several steps must occur. Please outline these steps Part I: How does depolarization occur (i.e what is resting membrane voltage, all the steps, from chemical messengers, to the types of ion channels and ions) Part II: How does repolarization occur (all the steps, what channels open, close, ions involved) etc Part III: How does hyperpolarization occur and how does cell return back to original resting voltage
