Why do ion channels contribute to faster cellular responses than other signaling
mechanisms, such as GPCR-mediated signaling?
by

1 Answer

Answer :

Ion channels generate electrical signals, which signals travel much more rapidly than
chemical signals that depend on the process of molecular diffusion. An electrical
signal can traverse the entire length of a nerve cell within milliseconds.
