the rapid change in membrane potential that occurs when a ligand binds to an ionotropic receptor is caused by... a) the rapid gatiing of the ion channel by a G protein b) the rapid G protein response that indirectly links receptor to channel c) the G protein amplification that causes the rapid channel response d) the presense of one protein that functions as both a receptor and an ion channel e) none of the above

Solution

The answer is: d) the presense of one protein that functions as both a receptor and an ion channel.

The rapid change in membrane potential that occurs when a ligand binds to an ionotropic receptor is caused by the presense of one protein that functions as both a receptor and an ion channel.
