What is the function of the neurotransmitter in the transmission of impulses at a chemical synapse?
To generate the action potential in the postsynaptic neuron.
To convert the electrical signal of the action potential into a chemical signal.
To bind to the receptors on the presynaptic neuron, allowing the impulse to propagate.
To increase the concentration of calcium ions in the synaptic cleft.
Answers (1)
The action potential's electrical signal is changed into a chemical signal by the neurotransmitter, which is its main purpose. The neurotransmitter is released into the synaptic cleft when the vesicles carrying them fuse with the presynaptic membrane, where it binds to receptors on the postsynaptic membrane. As a result of this interaction, a chemical signal is produced that may cause the postsynaptic neuron's ion channels to open or close, altering the membrane potential and perhaps resulting in the generation of an action potential.
Option 2 is the correct answer.
