Why are the receptors on the postsynaptic neuron more important than the neurotransmitter released at the synapse for the response of the postsynaptic neuron?
The postsynaptic neuron is the neuron that receives the
neurotransmitter that crosses the synapse and they may experience
and action potential if the neurotransmitter is strong. Synaptic
neuron generally works through the temporal summation as well as
spatial summation. In the synapse presynaptic part is located in
the axon part and located on the dendrite or Soma. They also
exchange information with the synaptic neurons that respond to
synaptic activity during regulation.
Postsynaptic neuron on the receptors is very important as compared
to a neurotransmitter that released at the synapse for the
postsynaptic neuron. These are those molecules that combined with
the receptors on the supportive cell. Based on the release of
chemicals from one neuron, this leads to cause the response with
the transmission of chemicals. Synaptic neurons are also
responsible to transfer the information from one postsynaptic
receptor to another.
In the chemical synapse, action potential leads to cause the
release of neurotransmitters in the synaptic cleft. Binding of
postsynaptic receptor the neurotransmitter cause the inhibitory and
excitatory potentials by polarizing and hyperpolarising of the
membrane.

Describe what happens in a postsynaptic cell when an excitatory neurotransmitter is released into the synapse by a presynaptic neuron. Describe what happens in a pos-synaptic cell when an inhibitory neurotransmitter is released into the synapse by a presynaptic neuron.

INFORMATION ABOUT IMAGE G FOR QUESTIONS 12-15: GABAB receptors (GABABRs) are G-protein-coupled receptors that can be found on both pre- and postsynaptic neurons. When they are activated by GABA, they can have a range of effects. For the synapse you are studying in the following questions, the effects of GABABRs are indicated in IMAGE G. You are doing a series of experiments in which you are recording from the pre- and postsynaptic cell at a synapse. The experiments described below...

Consider the neuromuscular junction between a pre-synaptic neuron and the diaphragm muscle. Acetylcholine is a neurotransmitter that is released from the presynaptic neuron to induce muscle contraction in the post-synaptic muscle cell. Which of the following would be an effect of tetrodotoxin? A. More acetylcholine in the synapse of the neuromuscular junction with the diaphragm B. Less acetylcholine in the synapse of the neuromuscular junction with the diaphragm
Once a neurotransmitter is released into the synapse, it eventually must be inactivated or else it will continue to have an effect on the postsynaptic cell. There are two major methods of neurotransmitter activation. Briefly explain each.
QUESTION 12 When the neurotransmitter binds to receptors on a postsynaptic ions to influx the membrane, it results in depolarization by allowing ion gates open, allowing it to cell, followed by repolarization when exit the cell membrane.
