Neurotransmitters Affect Postsynaptic Cells By

Question

Neurotransmitters affect postsynaptic cells by
A) initiating signal transduction pathways in the cells.
B) causing molecular changes in the cells.
C) affecting ion-channel proteins.
D) altering the permeability of the cells.
E) All of these options are correct.

Accepted Answer

All of these options are correct because neurotransmitters initiate signal transduction pathways, cause molecular changes such as gene expression, affect ion-channel proteins by either opening or closing them, and alter the permeability of cells to ions such as sodium, potassium, or chloride.
