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 they are activated by a chemical (the ligand) binding to the receptor and causing an opening of the pore/channel that allows ions to flow into or out of the cell.
