Metabotropic receptors:
A)Trigger EPSPs whose time course is mainly determined by the resistor-capacitor (RC)circuit (i.e.,passive electrical)properties of the cell membrane.
B)Trigger EPSPs that last approximately 10 msec.
C)Are coupled to a G protein.
D)Have only one significant action,which is to cause voltage changes (postsynaptic potentials [PSPs]).

Question

Quizplus · Accepted Answer

Metabotropic receptors are coupled to G proteins, which can lead to a variety of downstream effects such as second messenger signaling, ion channel modulation, and changes in gene expression. They do not directly trigger EPSPs or cause voltage changes (PSPs).
