Ion channel that are always open are called?
leak channes
Are the pores of ion channels always open?
Depends on the ion channel. Heart muscle cells have both leaky channels that are open all the time and other channels that only open at certain voltages across the cell membrane.
Which ion channels open in response to a change in membrane potential?
voltage-gated ion channels
Describe gating mechanism existing in channels?
G protein-gated ion channels are specific ion channels located in the plasma membrane.
Can any ion pass through the ion channels?
yes it can

Are ion channels carbohydrates?
Ion channels are not carbohydrates but are pore-forming membrane proteins. One of their functions is to include establishing a resting membrane potential.
What structures in the cell membrane function as ion channels?
protein channels
