The specific receptors for neurotransmitters in a synapse are present on ________.

The correct answer is Post-synaptic membrane.

In a chemical synapse, an electrical impulse travels down the axon of the presynaptic neuron and triggers the release of neurotransmitter molecules into the synaptic cleft.

These neurotransmitters diffuse across the cleft and must bind to specific protein receptors in order to transmit the signal.

The receptors are embedded in the membrane of the neuron that receives the signal – the postsynaptic neuron. When a neurotransmitter binds to its receptor on the postsynaptic membrane, it causes ion channels to open or initiates intracellular signaling pathways, leading to a change in the postsynaptic cell’s membrane potential.

Thus, the specific receptors for neurotransmitters are located on the post‑synaptic membrane, not on the presynaptic membrane, myelin sheath, or Schwann cell.
