Question 1

Define action potential. (chat)

Answer 1

An action potential is a rapid, temporary change in the electrical charge across a cell membrane, typically in neurons or muscle cells. It occurs when a cell receives a stimulus, causing voltage-gated ion channels to open and allow ions to flow in and out, leading to a sudden depolarization and then repolarization. This process allows the cell to transmit electrical signals.

Question 2

What is the action potential?

An action potential is a rapid, temporary change in the electrical charge across a cell membrane, typically in neurons or muscle cells. It occurs when a cell receives a stimulus, causing voltage-gated ion channels to open and allow ions to flow in and out, leading to a sudden depolarization and then repolarization.
