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