Question

Anatomy & Physiology Question:

Drug addiction has reduced the number of receptors in the addict's neural synapses. How will this affect signal transduction at the synapse?

A.) Less neurotransmitter will be produced by the presynaptic cell.
B.) More neurotransmitter will be produce by the presynaptic cell.
C.) More ion channels will open in the postsynaptic cell.
D.) Fewer ion channels will open in the postsynaptic cell.

Answer 1

D.) Fewer ion channels will open in the postsynaptic cell.

Step-by-step explanation:

The correct answer is option D, because neurotransmitters bind to receptors which are locate on dendrites, causing ion channels open. In addition, the postsynaptic membrane is the membrane that receives the signal. So, if fewer ion channels will open in the postsynaptic cell, means the number of receptors will be reduced, because the membrane will receive less.

Answer 2

This will affect signal transduction at the synapse by fewer ion channels will open in the postsynaptic. The correct answer is D.
