Ionotropic Receptors are Found at Synapses Operated Via

Question

Ionotropic receptors are found at synapses operated via
A) ligand-gated ion channels.
B) second-messenger-gated ion channels.
C) electrical synapses.
D) inhibitory, but not excitatory, synapses.
E) excitatory, but not inhibitory, synapses.

Accepted Answer

Ionotropic receptors are ligand-gated ion channels, meaning that they open in response to a specific neurotransmitter binding to the receptor. This allows ions to flow through the channel, resulting in a rapid change in the membrane potential of the postsynaptic neuron.
