Which cellular response follows activation of a ligand-gated ion channel?
A) direct regulation of gene expression
B) generation of an electrical signal
C) activation of a phosphorylation cascade
D) activation of a second messenger pathway
E) direct activation of a kinase

Question

Quizplus · Accepted Answer

Ligand-gated ion channels, when activated by a ligand, allow ions to flow across the membrane, creating an electrical signal. This is a direct and immediate response, unlike the other options which involve more complex and indirect cellular processes.
