Question

Explain how resting potential is maintained and how an action potential occurs.

Answer 1

Answer:

resting potential is maintained by ion leaks and ion pumps

action potential occurs by:

- depolarization

-repolarization

-hyperpolarization

Explanation:

Answer 2

Sodium-potassium pumps move two potassium ions inside the cell as three sodium ions are pumped out to maintain the negatively-charged membrane inside the cell; this helps maintain the resting potential.
