Explain how leak channels and gated channels differ
What will be an ideal response?
Leak channels are always open while gated channels are closed at rest. Gated channels only open in response to certain stimuli. Leak channels allow ions to follow their gradient into or out of the cell. Gated channels may be ligand-gated, voltage-gated, or mechanically gated. Ligand-gated channels open in response to a chemical binding to the channel while voltage-gated channels open or close in response to changes in voltage across the membrane. Mechanically gated channels open in response to mechanical stimulation such as stretch, pressure, or vibrations.
