What would happen if inhibitory postsynaptic potentials did not exist

A)  Antagonism would not occur. 
B)  Neurons would be more likely to depolarize. 
C)  Neurons would be more resistant to depolarization. 
D)  Reuptake would not occur.

Inhibitory Postsynaptic Potentials

Electrical changes in the membrane of a postsynaptic neuron that make the neuron less likely to generate an action potential.

Depolarize

In social contexts, to reduce or neutralize extreme views or tensions between opposing parties or viewpoints.

Reuptake

The process by which neurotransmitters are absorbed by the nerve cell that released them, thereby terminating the signal between nerve cells.
