Answer #1

The differences between chemically (ligand)- gated channels and voltage-gated channels are given below:

Voltage-gated channels Ligand-gated channels
It opens in response to voltage difference present across the membrane. It opens in response to a ligand binding to them or some chemical signal.
It is ion-specific. It is not specific.
Example- Calcium channels, sodium channels, potassium channels, etc. Examples- Nicotinic cholinergic receptor, acetylcholine receptors, etc.
