Verified
The same neurotransmitter binds to a postsynaptic cell but produces a variety of different effects. What does this mean?
A) The postsynaptic cell is expressing different types of receptors for the same neurotransmitter.
B) The strength of the neurotransmitter varies.
C) The amount of neurotransmitter released produces varying effects.
D) The size of the postsynaptic cell makes a difference in neurotransmitter effects.
E) The neuron must be dying.
Neurotransmitter Effects
The impacts or actions exerted by neurotransmitters, which are chemicals responsible for transmitting signals across a chemical synapse between neurons or between neurons and muscles.
Receptors
Proteins located on the surface of or within cells, which bind to specific molecules, triggering a physiological response.
Postsynaptic Cell
A neuron or muscle cell that receives signals from a presynaptic neuron at a synapse.

Final Answer :
A
Explanation :
The variety of effects produced by the same neurotransmitter on a postsynaptic cell is due to the cell expressing different types of receptors for that neurotransmitter. Each receptor type can initiate a different response when bound by the neurotransmitter.
