I’m not sure with the question
Binding of a signaling molecule to ligand-gated ion channel leads directly to a change in the distribution of ions on opposite sides of the membrane
<u>Explanation:</u>
The ligand-gated-ion-channel is trans membrane protein buildings that conduction course through the channel pores in light of the official of a neurotransmitter. They are not quite the same as voltage - gated - ion - channels, which are delicate to film possibilities, and G-protein coupled receptors (GPCR's), which utilize second messengers.
These ion channels, additionally ordinarily referred to as ionotropic receptors, are a gathering of trans membrane -ion-channel proteins which open to permit ions, for example,
and potentially
to go through the layer in light of the official of a synthetic errand person, for example, a neurotransmitter.
The primary coil has more turns than the secondary coil. so D.
I think the answer is digestive system
