Suppose a particular neurotransmitter causes an IPSP in postsynaptic cell X and an EPSP in postsynaptic cell Y . A likely explanation is that A. the threshold value in the postsynaptic membrane is different for cell X and cell Y. B. the axon of cell X is myelinated, but that of cell Y is not. C. only cell Y produces an enzyme that terminates the activity of the neurotransmitter. D. cells X and Y express different receptor molecules for this particular neurotransmitter.

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.

What is meant by neurotransmitter?

  • 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.
