Assume that a specific neurotransmitter causes an IPSP in postsynaptic cell X and an EPSP in postsynaptic cell Y. One possible explanation is that cells X and Y express different neurotransmitter receptor molecules.
<h3 /><h3>What is meant by neurotransmitter?</h3>
- A neurotransmitter is a signaling molecule secreted by a neuron to influence another cell across a synapse.
- Another neuron, a gland, or a muscle cell could be the cell receiving the signal, which could be any major body part or target cell.
- A neurotransmitter is a chemical messenger that transports, amplifies, and balances signals across the body between neurons (also known as nerve cells).
- Assume that a particular neurotransmitter produces an IPSP in postsynaptic cell X and an EPSP in postsynaptic cell Y.
- Cells X and Y may express different neurotransmitter receptor molecules, which is one possible explanation.
Therefore, the correct answer is option d. cells X and Y express different receptor molecules for this particular neurotransmitter.
