Binding of a signalling molecule to which type of receptor leads directly to a change in the distribution of ions on opposite sides of the membrane?

B)G protein-coupled receptor
C)phosphorylated receptor tyrosine kinase dimer
D)ligand-gated ion channel
E)intracellular receptor

Question

Quizplus · Accepted Answer

Ligand-gated ion channels bind to a specific signalling molecule, which leads to the opening or closing of the channel, and allows a specific ion to pass through the membrane, resulting in a rapid change in ion distribution on opposite sides of the membrane.
