Binding of a signaling molecule to which type of receptor leads directly to a change in distribution of ions on opposite sides of the membrane?
A)receptor tyrosine kinase
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 directly allow ions to pass through the membrane in response to ligand binding, leading to a change in ion distribution on opposite sides of the membrane. Receptor tyrosine kinases, phosphorylated receptor tyrosine kinase dimers, G protein-coupled receptors, and intracellular receptors do not directly affect ion distribution.
