In response to binding a neurotransmitter, a postsynaptic cell can
◦ only open chemically gated ion channels, causing graded potentials known as fast synaptic potentials.
◦ only close ion channels through G proteins and second messenger systems, producing slow responses.
◦ open chemically gated ion channels, causing graded potentials known as fast synaptic potentials, close ion channels through G proteins and second messenger systems, producing slow responses, and regulate protein synthesis and affect the metabolic activities of the postsynaptic cell.
◦ only regulate protein synthesis and affect the metabolic activities of the postsynaptic cell.
