Question

which of the following best describes the fourth step of the neurotransmission process?
the release of neuromodulators
the release of neurotransmitters into the synapse
the binding of neurotransmitters to receptors on the post - synaptic neuron or target cell
the synthesis and packaging of neurotransmitters in the pre - synaptic neuron

Explanation:

The neurotransmission process steps typically are: 1. Synthesis and packaging of neurotransmitters in pre - synaptic neuron, 2. Transport and storage, 3. Release of neurotransmitters into synapse, 4. Binding of neurotransmitters to receptors on post - synaptic neuron/target cell. The first option is incorrect as neuromodulators are different from neurotransmitters in this context. The second option is the third step. The fourth option is the first step. So the correct description for the fourth step is the binding of neurotransmitters to receptors on the post - synaptic neuron or target cell.

Answer:

the binding of neurotransmitters to receptors on the post - synaptic neuron or target cell
