ANSWER :
The effect of a neurotransmitter on a postsynaptic neuron is determined by the type of receptors on the postsynaptic membrane. If it binds to metabotropic receptors then cause cytoplasmic effect such as activation of genes, enzymes and channels, while binding of neurotransmitter to the ionotropic membrane receptors of postsynaptic neuron then it alter the ionic permeability of the neuron and cause to inhibition or excitation of action potential correspondingly. Hence option (c) is the correct answer.

If necessary, refer to Animation: Chemical Synapses. When an action potential reaches the axon terminal: sodium ions are released from the axon terminal, enter the cell body of the postsynaptic neuron through its sodium channels, and may initiate an action potential in that neuron. neurotransmitter molecules are released from the axon terminal and bind to receptors on the postsynaptic neuron, causing either an inhibitory hyperpolarization or an excitatory depolarization. neurotransmitter molecules are released from the axon terminal, bind to and...

glutamatergic synapse that contains AMPA and NMDA receptors. You
stimulate the presynaptic neuron and record an EPSP. You then apply
ketamine to the synapse and allow enough time for it to have its
effect on the synapse (several minutes). Then you stimulate the
presynaptic neuron again and record the resulting EPSP. Which of
the following sets of plots indicates what your results would look
