Leak Ion Channels

Question

Leak ion channels:
A) open in response to changes in the membrane potential
B) are always open
C) open in response to neurotransmitters or other chemicals
D) are closed until opened by specific signals
E) are responsible for the generation of the action potential in neurons

Accepted Answer

Leak ion channels are always open, allowing ions to move across the cell membrane and contributing to the resting membrane potential of the cell. They do not open or close in response to specific signals but rather provide a constant pathway for ions.
