The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Components**: In a synapse, there are two main components: the presynaptic membrane (the terminal of the neuron that sends the signal) and the postsynaptic membrane (the part of the neuron that receives the signal). 2. **Role of Neurotransmitters**: Neurotransmitters are chemical messengers stored in synaptic vesicles located in the presynaptic membrane. When a nerve impulse reaches the presynaptic terminal, these neurotransmitters are released into the synaptic cleft (the gap between the two membranes). 3. **Binding to Receptors**: The released neurotransmitters travel across the synaptic cleft and bind to specific receptors located on the postsynaptic membrane. 4. **Opening of Ion Channels**: The binding of the neurotransmitter to its receptor causes ion channels in the postsynaptic membrane to open. This allows ions (such as sodium or calcium) to flow into the postsynaptic neuron. 5. **Generation of Postsynaptic Potential**: The influx of ions changes the electrical charge across the postsynaptic membrane, generating a new electrical potential known as the postsynaptic potential. This potential can lead to the generation of an action potential if it reaches a certain threshold. 6. **Conclusion**: Therefore, the new potential is generated in the postsynaptic membrane as a result of the binding of the neurotransmitter to its receptors. **Final Answer**: The new potential is generated in the **postsynaptic membrane**. ---
