During the transmission of a nerve impulse across a chemical synapse, what is the immediate physiological consequence of neurotransmitters binding to their specific receptors on the post-synaptic membrane?

Options

  1. AMovement of synaptic vesicles towards the pre-synaptic membrane
  2. BRelease of neurotransmitters into the synaptic cleft
  3. CGeneration of an action potential in the pre-synaptic neuron
  4. DOpening of specific ion channels

Correct answer

D. Opening of specific ion channels

Step-by-step solution

During synaptic transmission at a chemical synapse, the binding of neurotransmitters to their specific receptors on the post-synaptic membrane leads to the opening of specific ion channels. This opening allows the entry of ions, which can generate a new potential (either excitatory or inhibitory) in the post-synaptic neuron. The movement of synaptic vesicles and the release of neurotransmitters are pre-synaptic events that occur prior to receptor binding, while the action potential in the pre-synaptic neuron is the
