A) only open chemically gated ion channels, causing graded potentials known as fast synaptic potentials.
B) only close ion channels via G proteins and second messenger systems, producing slow responses.
C) only regulate protein synthesis and affect the metabolic activities of the postsynaptic cell.
D) open chemically gated ion channels, causing graded potentials known as fast synaptic potentials and regulate protein synthesis and affect the metabolic activities of the postsynaptic cell.
E) open chemically gated ion channels, causing graded potentials known as fast synaptic potentials, close ion channels via G proteins and second messenger systems, producing slow responses, and regulate protein synthesis and affect the metabolic activities of the postsynaptic cell.

Question

Quizplus · Accepted Answer

In response to neurotransmitter binding, a postsynaptic cell can exhibit a range of responses, including opening chemically gated ion channels for fast synaptic potentials, closing ion channels via G proteins and second messenger systems for slower responses, and regulating protein synthesis to affect metabolic activities. This demonstrates the versatility of neurotransmitter action beyond simple ion channel modulation.
